Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537248, here are decompositions:
- 5 + 31537243 = 31537248
- 19 + 31537229 = 31537248
- 47 + 31537201 = 31537248
- 97 + 31537151 = 31537248
- 101 + 31537147 = 31537248
- 151 + 31537097 = 31537248
- 199 + 31537049 = 31537248
- 257 + 31536991 = 31537248
Showing the first eight; more decompositions exist.
