Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461360, here are decompositions:
- 11 + 31461349 = 31461360
- 17 + 31461343 = 31461360
- 19 + 31461341 = 31461360
- 59 + 31461301 = 31461360
- 67 + 31461293 = 31461360
- 79 + 31461281 = 31461360
- 107 + 31461253 = 31461360
- 131 + 31461229 = 31461360
Showing the first eight; more decompositions exist.
