Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541128, here are decompositions:

  • 11 + 31541117 = 31541128
  • 89 + 31541039 = 31541128
  • 107 + 31541021 = 31541128
  • 137 + 31540991 = 31541128
  • 149 + 31540979 = 31541128
  • 167 + 31540961 = 31541128
  • 257 + 31540871 = 31541128
  • 401 + 31540727 = 31541128

Showing the first eight; more decompositions exist.
