Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544174, here are decompositions:

  • 3 + 31544171 = 31544174
  • 7 + 31544167 = 31544174
  • 43 + 31544131 = 31544174
  • 97 + 31544077 = 31544174
  • 163 + 31544011 = 31544174
  • 271 + 31543903 = 31544174
  • 331 + 31543843 = 31544174
  • 397 + 31543777 = 31544174

Showing the first eight; more decompositions exist.
