Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474690, here are decompositions:
- 3 + 31474687 = 31474690
- 17 + 31474673 = 31474690
- 89 + 31474601 = 31474690
- 113 + 31474577 = 31474690
- 131 + 31474559 = 31474690
- 257 + 31474433 = 31474690
- 293 + 31474397 = 31474690
- 347 + 31474343 = 31474690
Showing the first eight; more decompositions exist.
