Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474966, here are decompositions:
- 137 + 31474829 = 31474966
- 233 + 31474733 = 31474966
- 293 + 31474673 = 31474966
- 389 + 31474577 = 31474966
- 563 + 31474403 = 31474966
- 569 + 31474397 = 31474966
- 647 + 31474319 = 31474966
- 659 + 31474307 = 31474966
Showing the first eight; more decompositions exist.
