Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75456, here are decompositions:
- 19 + 75437 = 75456
- 53 + 75403 = 75456
- 67 + 75389 = 75456
- 79 + 75377 = 75456
- 89 + 75367 = 75456
- 103 + 75353 = 75456
- 109 + 75347 = 75456
- 127 + 75329 = 75456
Showing the first eight; more decompositions exist.
