Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474810, here are decompositions:
- 47 + 31474763 = 31474810
- 89 + 31474721 = 31474810
- 137 + 31474673 = 31474810
- 233 + 31474577 = 31474810
- 239 + 31474571 = 31474810
- 251 + 31474559 = 31474810
- 467 + 31474343 = 31474810
- 491 + 31474319 = 31474810
Showing the first eight; more decompositions exist.
