Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497190, here are decompositions:

  • 109 + 2147497081 = 2147497190
  • 151 + 2147497039 = 2147497190
  • 193 + 2147496997 = 2147497190
  • 211 + 2147496979 = 2147497190
  • 229 + 2147496961 = 2147497190
  • 331 + 2147496859 = 2147497190
  • 337 + 2147496853 = 2147497190
  • 373 + 2147496817 = 2147497190

Showing the first eight; more decompositions exist.
