Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471418, here are decompositions:
- 7 + 31471411 = 31471418
- 31 + 31471387 = 31471418
- 61 + 31471357 = 31471418
- 211 + 31471207 = 31471418
- 271 + 31471147 = 31471418
- 367 + 31471051 = 31471418
- 421 + 31470997 = 31471418
- 571 + 31470847 = 31471418
Showing the first eight; more decompositions exist.
