Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466638, here are decompositions:
- 11 + 31466627 = 31466638
- 41 + 31466597 = 31466638
- 89 + 31466549 = 31466638
- 251 + 31466387 = 31466638
- 257 + 31466381 = 31466638
- 311 + 31466327 = 31466638
- 347 + 31466291 = 31466638
- 389 + 31466249 = 31466638
Showing the first eight; more decompositions exist.
