Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474858, here are decompositions:
- 29 + 31474829 = 31474858
- 137 + 31474721 = 31474858
- 167 + 31474691 = 31474858
- 257 + 31474601 = 31474858
- 281 + 31474577 = 31474858
- 461 + 31474397 = 31474858
- 557 + 31474301 = 31474858
- 641 + 31474217 = 31474858
Showing the first eight; more decompositions exist.
