Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506274, here are decompositions:
- 3 + 31506271 = 31506274
- 11 + 31506263 = 31506274
- 101 + 31506173 = 31506274
- 281 + 31505993 = 31506274
- 347 + 31505927 = 31506274
- 353 + 31505921 = 31506274
- 431 + 31505843 = 31506274
- 461 + 31505813 = 31506274
Showing the first eight; more decompositions exist.
