Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527576, here are decompositions:
- 7 + 31527569 = 31527576
- 43 + 31527533 = 31527576
- 53 + 31527523 = 31527576
- 79 + 31527497 = 31527576
- 163 + 31527413 = 31527576
- 233 + 31527343 = 31527576
- 383 + 31527193 = 31527576
- 419 + 31527157 = 31527576
Showing the first eight; more decompositions exist.
