Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475556, here are decompositions:
- 67 + 31475489 = 31475556
- 97 + 31475459 = 31475556
- 103 + 31475453 = 31475556
- 113 + 31475443 = 31475556
- 127 + 31475429 = 31475556
- 149 + 31475407 = 31475556
- 163 + 31475393 = 31475556
- 239 + 31475317 = 31475556
Showing the first eight; more decompositions exist.
