Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541162, here are decompositions:
- 61 + 31541101 = 31541162
- 223 + 31540939 = 31541162
- 241 + 31540921 = 31541162
- 349 + 31540813 = 31541162
- 379 + 31540783 = 31541162
- 439 + 31540723 = 31541162
- 463 + 31540699 = 31541162
- 661 + 31540501 = 31541162
Showing the first eight; more decompositions exist.
