Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528652, here are decompositions:
- 19 + 31528633 = 31528652
- 31 + 31528621 = 31528652
- 73 + 31528579 = 31528652
- 79 + 31528573 = 31528652
- 151 + 31528501 = 31528652
- 193 + 31528459 = 31528652
- 373 + 31528279 = 31528652
- 439 + 31528213 = 31528652
Showing the first eight; more decompositions exist.
