Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529232, here are decompositions:
- 13 + 31529219 = 31529232
- 19 + 31529213 = 31529232
- 83 + 31529149 = 31529232
- 151 + 31529081 = 31529232
- 179 + 31529053 = 31529232
- 239 + 31528993 = 31529232
- 263 + 31528969 = 31529232
- 379 + 31528853 = 31529232
Showing the first eight; more decompositions exist.
