Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586544, here are decompositions:
- 7 + 31586537 = 31586544
- 43 + 31586501 = 31586544
- 47 + 31586497 = 31586544
- 61 + 31586483 = 31586544
- 71 + 31586473 = 31586544
- 83 + 31586461 = 31586544
- 97 + 31586447 = 31586544
- 137 + 31586407 = 31586544
Showing the first eight; more decompositions exist.
