Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87630, here are decompositions:
- 7 + 87623 = 87630
- 17 + 87613 = 87630
- 41 + 87589 = 87630
- 43 + 87587 = 87630
- 47 + 87583 = 87630
- 71 + 87559 = 87630
- 73 + 87557 = 87630
- 83 + 87547 = 87630
Showing the first eight; more decompositions exist.
