Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64646, here are decompositions:
- 13 + 64633 = 64646
- 19 + 64627 = 64646
- 37 + 64609 = 64646
- 67 + 64579 = 64646
- 79 + 64567 = 64646
- 157 + 64489 = 64646
- 163 + 64483 = 64646
- 193 + 64453 = 64646
Showing the first eight; more decompositions exist.
