Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61820, here are decompositions:
- 7 + 61813 = 61820
- 97 + 61723 = 61820
- 103 + 61717 = 61820
- 139 + 61681 = 61820
- 163 + 61657 = 61820
- 193 + 61627 = 61820
- 211 + 61609 = 61820
- 277 + 61543 = 61820
Showing the first eight; more decompositions exist.
