Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133560, here are decompositions:
- 17 + 133543 = 133560
- 19 + 133541 = 133560
- 41 + 133519 = 133560
- 61 + 133499 = 133560
- 67 + 133493 = 133560
- 79 + 133481 = 133560
- 109 + 133451 = 133560
- 113 + 133447 = 133560
Showing the first eight; more decompositions exist.
