Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528692, here are decompositions:
- 23 + 31528669 = 31528692
- 59 + 31528633 = 31528692
- 71 + 31528621 = 31528692
- 79 + 31528613 = 31528692
- 113 + 31528579 = 31528692
- 191 + 31528501 = 31528692
- 193 + 31528499 = 31528692
- 233 + 31528459 = 31528692
Showing the first eight; more decompositions exist.
