Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72556, here are decompositions:
- 5 + 72551 = 72556
- 23 + 72533 = 72556
- 53 + 72503 = 72556
- 59 + 72497 = 72556
- 89 + 72467 = 72556
- 173 + 72383 = 72556
- 269 + 72287 = 72556
- 383 + 72173 = 72556
Showing the first eight; more decompositions exist.
