Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540676, here are decompositions:
- 7 + 31540669 = 31540676
- 19 + 31540657 = 31540676
- 103 + 31540573 = 31540676
- 313 + 31540363 = 31540676
- 337 + 31540339 = 31540676
- 367 + 31540309 = 31540676
- 379 + 31540297 = 31540676
- 463 + 31540213 = 31540676
Showing the first eight; more decompositions exist.
