Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61788, here are decompositions:
- 7 + 61781 = 61788
- 31 + 61757 = 61788
- 37 + 61751 = 61788
- 59 + 61729 = 61788
- 71 + 61717 = 61788
- 101 + 61687 = 61788
- 107 + 61681 = 61788
- 131 + 61657 = 61788
Showing the first eight; more decompositions exist.
