Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529400, here are decompositions:
- 41 + 31529359 = 31529400
- 47 + 31529353 = 31529400
- 53 + 31529347 = 31529400
- 79 + 31529321 = 31529400
- 127 + 31529273 = 31529400
- 131 + 31529269 = 31529400
- 151 + 31529249 = 31529400
- 157 + 31529243 = 31529400
Showing the first eight; more decompositions exist.
