Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537302, here are decompositions:
- 29 + 31537273 = 31537302
- 31 + 31537271 = 31537302
- 59 + 31537243 = 31537302
- 73 + 31537229 = 31537302
- 79 + 31537223 = 31537302
- 101 + 31537201 = 31537302
- 149 + 31537153 = 31537302
- 151 + 31537151 = 31537302
Showing the first eight; more decompositions exist.
