Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77542, here are decompositions:
- 29 + 77513 = 77542
- 53 + 77489 = 77542
- 71 + 77471 = 77542
- 173 + 77369 = 77542
- 191 + 77351 = 77542
- 251 + 77291 = 77542
- 263 + 77279 = 77542
- 281 + 77261 = 77542
Showing the first eight; more decompositions exist.
