Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541042, here are decompositions:
- 3 + 31541039 = 31541042
- 103 + 31540939 = 31541042
- 229 + 31540813 = 31541042
- 349 + 31540693 = 31541042
- 373 + 31540669 = 31541042
- 541 + 31540501 = 31541042
- 571 + 31540471 = 31541042
- 601 + 31540441 = 31541042
Showing the first eight; more decompositions exist.
