Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72832, here are decompositions:
- 113 + 72719 = 72832
- 131 + 72701 = 72832
- 281 + 72551 = 72832
- 401 + 72431 = 72832
- 449 + 72383 = 72832
- 479 + 72353 = 72832
- 491 + 72341 = 72832
- 563 + 72269 = 72832
Showing the first eight; more decompositions exist.
