Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87784, here are decompositions:
- 17 + 87767 = 87784
- 41 + 87743 = 87784
- 83 + 87701 = 87784
- 101 + 87683 = 87784
- 113 + 87671 = 87784
- 197 + 87587 = 87784
- 227 + 87557 = 87784
- 293 + 87491 = 87784
Showing the first eight; more decompositions exist.
