Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535504, here are decompositions:

  • 37 + 31535467 = 31535504
  • 127 + 31535377 = 31535504
  • 163 + 31535341 = 31535504
  • 193 + 31535311 = 31535504
  • 241 + 31535263 = 31535504
  • 271 + 31535233 = 31535504
  • 277 + 31535227 = 31535504
  • 331 + 31535173 = 31535504

Showing the first eight; more decompositions exist.
