Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537122, here are decompositions:
- 73 + 31537049 = 31537122
- 79 + 31537043 = 31537122
- 83 + 31537039 = 31537122
- 131 + 31536991 = 31537122
- 139 + 31536983 = 31537122
- 163 + 31536959 = 31537122
- 179 + 31536943 = 31537122
- 251 + 31536871 = 31537122
Showing the first eight; more decompositions exist.
