Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147396220, here are decompositions:

  • 7 + 2147396213 = 2147396220
  • 17 + 2147396203 = 2147396220
  • 31 + 2147396189 = 2147396220
  • 41 + 2147396179 = 2147396220
  • 61 + 2147396159 = 2147396220
  • 157 + 2147396063 = 2147396220
  • 163 + 2147396057 = 2147396220
  • 181 + 2147396039 = 2147396220

Showing the first eight; more decompositions exist.
