Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529102, here are decompositions:
- 13 + 31529089 = 31529102
- 109 + 31528993 = 31529102
- 193 + 31528909 = 31529102
- 271 + 31528831 = 31529102
- 373 + 31528729 = 31529102
- 379 + 31528723 = 31529102
- 433 + 31528669 = 31529102
- 523 + 31528579 = 31529102
Showing the first eight; more decompositions exist.
