Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77572, here are decompositions:
- 3 + 77569 = 77572
- 23 + 77549 = 77572
- 29 + 77543 = 77572
- 59 + 77513 = 77572
- 83 + 77489 = 77572
- 101 + 77471 = 77572
- 233 + 77339 = 77572
- 281 + 77291 = 77572
Showing the first eight; more decompositions exist.
