Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79572, here are decompositions:
- 11 + 79561 = 79572
- 13 + 79559 = 79572
- 23 + 79549 = 79572
- 41 + 79531 = 79572
- 79 + 79493 = 79572
- 139 + 79433 = 79572
- 149 + 79423 = 79572
- 173 + 79399 = 79572
Showing the first eight; more decompositions exist.
