Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474954, here are decompositions:
- 23 + 31474931 = 31474954
- 191 + 31474763 = 31474954
- 233 + 31474721 = 31474954
- 263 + 31474691 = 31474954
- 281 + 31474673 = 31474954
- 353 + 31474601 = 31474954
- 383 + 31474571 = 31474954
- 521 + 31474433 = 31474954
Showing the first eight; more decompositions exist.
