Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87702, here are decompositions:
- 5 + 87697 = 87702
- 11 + 87691 = 87702
- 19 + 87683 = 87702
- 23 + 87679 = 87702
- 31 + 87671 = 87702
- 53 + 87649 = 87702
- 59 + 87643 = 87702
- 61 + 87641 = 87702
Showing the first eight; more decompositions exist.
