Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72564, here are decompositions:
- 5 + 72559 = 72564
- 13 + 72551 = 72564
- 17 + 72547 = 72564
- 31 + 72533 = 72564
- 61 + 72503 = 72564
- 67 + 72497 = 72564
- 71 + 72493 = 72564
- 83 + 72481 = 72564
Showing the first eight; more decompositions exist.
