Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61778, here are decompositions:
- 61 + 61717 = 61778
- 97 + 61681 = 61778
- 127 + 61651 = 61778
- 151 + 61627 = 61778
- 271 + 61507 = 61778
- 307 + 61471 = 61778
- 337 + 61441 = 61778
- 397 + 61381 = 61778
Showing the first eight; more decompositions exist.
