Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541012, here are decompositions:
- 73 + 31540939 = 31541012
- 199 + 31540813 = 31541012
- 229 + 31540783 = 31541012
- 313 + 31540699 = 31541012
- 439 + 31540573 = 31541012
- 523 + 31540489 = 31541012
- 541 + 31540471 = 31541012
- 571 + 31540441 = 31541012
Showing the first eight; more decompositions exist.
