Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541102, here are decompositions:
- 31 + 31541071 = 31541102
- 163 + 31540939 = 31541102
- 181 + 31540921 = 31541102
- 379 + 31540723 = 31541102
- 409 + 31540693 = 31541102
- 433 + 31540669 = 31541102
- 601 + 31540501 = 31541102
- 613 + 31540489 = 31541102
Showing the first eight; more decompositions exist.
