Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527612, here are decompositions:
- 29 + 31527583 = 31527612
- 43 + 31527569 = 31527612
- 71 + 31527541 = 31527612
- 79 + 31527533 = 31527612
- 89 + 31527523 = 31527612
- 113 + 31527499 = 31527612
- 131 + 31527481 = 31527612
- 199 + 31527413 = 31527612
Showing the first eight; more decompositions exist.
