Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61688, here are decompositions:
- 7 + 61681 = 61688
- 31 + 61657 = 61688
- 37 + 61651 = 61688
- 61 + 61627 = 61688
- 79 + 61609 = 61688
- 127 + 61561 = 61688
- 181 + 61507 = 61688
- 271 + 61417 = 61688
Showing the first eight; more decompositions exist.
