Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529250, here are decompositions:
- 7 + 31529243 = 31529250
- 31 + 31529219 = 31529250
- 37 + 31529213 = 31529250
- 83 + 31529167 = 31529250
- 101 + 31529149 = 31529250
- 163 + 31529087 = 31529250
- 197 + 31529053 = 31529250
- 257 + 31528993 = 31529250
Showing the first eight; more decompositions exist.
