Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87624, here are decompositions:
- 11 + 87613 = 87624
- 37 + 87587 = 87624
- 41 + 87583 = 87624
- 67 + 87557 = 87624
- 71 + 87553 = 87624
- 83 + 87541 = 87624
- 101 + 87523 = 87624
- 107 + 87517 = 87624
Showing the first eight; more decompositions exist.
