Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72576, here are decompositions:
- 17 + 72559 = 72576
- 29 + 72547 = 72576
- 43 + 72533 = 72576
- 73 + 72503 = 72576
- 79 + 72497 = 72576
- 83 + 72493 = 72576
- 107 + 72469 = 72576
- 109 + 72467 = 72576
Showing the first eight; more decompositions exist.
