Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87766, here are decompositions:
- 23 + 87743 = 87766
- 47 + 87719 = 87766
- 83 + 87683 = 87766
- 137 + 87629 = 87766
- 179 + 87587 = 87766
- 227 + 87539 = 87766
- 257 + 87509 = 87766
- 293 + 87473 = 87766
Showing the first eight; more decompositions exist.
