Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527636, here are decompositions:
- 53 + 31527583 = 31527636
- 59 + 31527577 = 31527636
- 67 + 31527569 = 31527636
- 103 + 31527533 = 31527636
- 113 + 31527523 = 31527636
- 137 + 31527499 = 31527636
- 139 + 31527497 = 31527636
- 223 + 31527413 = 31527636
Showing the first eight; more decompositions exist.
