Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524386, here are decompositions:

  • 43 + 31524343 = 31524386
  • 109 + 31524277 = 31524386
  • 163 + 31524223 = 31524386
  • 193 + 31524193 = 31524386
  • 337 + 31524049 = 31524386
  • 373 + 31524013 = 31524386
  • 433 + 31523953 = 31524386
  • 547 + 31523839 = 31524386

Showing the first eight; more decompositions exist.
