Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541136, here are decompositions:

  • 7 + 31541129 = 31541136
  • 19 + 31541117 = 31541136
  • 23 + 31541113 = 31541136
  • 89 + 31541047 = 31541136
  • 97 + 31541039 = 31541136
  • 157 + 31540979 = 31541136
  • 197 + 31540939 = 31541136
  • 269 + 31540867 = 31541136

Showing the first eight; more decompositions exist.
