Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87708, here are decompositions:
- 7 + 87701 = 87708
- 11 + 87697 = 87708
- 17 + 87691 = 87708
- 29 + 87679 = 87708
- 37 + 87671 = 87708
- 59 + 87649 = 87708
- 67 + 87641 = 87708
- 79 + 87629 = 87708
Showing the first eight; more decompositions exist.
