Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529484, here are decompositions:
- 5 + 31529479 = 31529484
- 13 + 31529471 = 31529484
- 37 + 31529447 = 31529484
- 53 + 31529431 = 31529484
- 71 + 31529413 = 31529484
- 131 + 31529353 = 31529484
- 137 + 31529347 = 31529484
- 163 + 31529321 = 31529484
Showing the first eight; more decompositions exist.
