Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64742, here are decompositions:
- 79 + 64663 = 64742
- 109 + 64633 = 64742
- 151 + 64591 = 64742
- 163 + 64579 = 64742
- 229 + 64513 = 64742
- 409 + 64333 = 64742
- 439 + 64303 = 64742
- 463 + 64279 = 64742
Showing the first eight; more decompositions exist.
