Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529454, here are decompositions:
- 7 + 31529447 = 31529454
- 23 + 31529431 = 31529454
- 41 + 31529413 = 31529454
- 101 + 31529353 = 31529454
- 107 + 31529347 = 31529454
- 181 + 31529273 = 31529454
- 197 + 31529257 = 31529454
- 211 + 31529243 = 31529454
Showing the first eight; more decompositions exist.
