Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473158, here are decompositions:

  • 7 + 31473151 = 31473158
  • 97 + 31473061 = 31473158
  • 127 + 31473031 = 31473158
  • 229 + 31472929 = 31473158
  • 271 + 31472887 = 31473158
  • 307 + 31472851 = 31473158
  • 331 + 31472827 = 31473158
  • 547 + 31472611 = 31473158

Showing the first eight; more decompositions exist.
