Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147400242, here are decompositions:

  • 3 + 2147400239 = 2147400242
  • 103 + 2147400139 = 2147400242
  • 241 + 2147400001 = 2147400242
  • 283 + 2147399959 = 2147400242
  • 433 + 2147399809 = 2147400242
  • 439 + 2147399803 = 2147400242
  • 523 + 2147399719 = 2147400242
  • 541 + 2147399701 = 2147400242

Showing the first eight; more decompositions exist.
