Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87774, here are decompositions:
- 7 + 87767 = 87774
- 23 + 87751 = 87774
- 31 + 87743 = 87774
- 53 + 87721 = 87774
- 73 + 87701 = 87774
- 83 + 87691 = 87774
- 103 + 87671 = 87774
- 131 + 87643 = 87774
Showing the first eight; more decompositions exist.
