Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553236, here are decompositions:

  • 3 + 31553233 = 31553236
  • 17 + 31553219 = 31553236
  • 23 + 31553213 = 31553236
  • 53 + 31553183 = 31553236
  • 59 + 31553177 = 31553236
  • 167 + 31553069 = 31553236
  • 173 + 31553063 = 31553236
  • 293 + 31552943 = 31553236

Showing the first eight; more decompositions exist.
