Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537002, here are decompositions:
- 11 + 31536991 = 31537002
- 19 + 31536983 = 31537002
- 43 + 31536959 = 31537002
- 59 + 31536943 = 31537002
- 131 + 31536871 = 31537002
- 139 + 31536863 = 31537002
- 173 + 31536829 = 31537002
- 179 + 31536823 = 31537002
Showing the first eight; more decompositions exist.
