Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87662, here are decompositions:
- 13 + 87649 = 87662
- 19 + 87643 = 87662
- 31 + 87631 = 87662
- 73 + 87589 = 87662
- 79 + 87583 = 87662
- 103 + 87559 = 87662
- 109 + 87553 = 87662
- 139 + 87523 = 87662
Showing the first eight; more decompositions exist.
