Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10780, here are decompositions:
- 41 + 10739 = 10780
- 47 + 10733 = 10780
- 71 + 10709 = 10780
- 89 + 10691 = 10780
- 113 + 10667 = 10780
- 149 + 10631 = 10780
- 167 + 10613 = 10780
- 173 + 10607 = 10780
Showing the first eight; more decompositions exist.
