Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471612, here are decompositions:
- 89 + 31471523 = 31471612
- 101 + 31471511 = 31471612
- 131 + 31471481 = 31471612
- 173 + 31471439 = 31471612
- 239 + 31471373 = 31471612
- 251 + 31471361 = 31471612
- 281 + 31471331 = 31471612
- 503 + 31471109 = 31471612
Showing the first eight; more decompositions exist.
