Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527588, here are decompositions:
- 5 + 31527583 = 31527588
- 11 + 31527577 = 31527588
- 19 + 31527569 = 31527588
- 47 + 31527541 = 31527588
- 67 + 31527521 = 31527588
- 89 + 31527499 = 31527588
- 97 + 31527491 = 31527588
- 107 + 31527481 = 31527588
Showing the first eight; more decompositions exist.
