Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87588, here are decompositions:
- 5 + 87583 = 87588
- 29 + 87559 = 87588
- 31 + 87557 = 87588
- 41 + 87547 = 87588
- 47 + 87541 = 87588
- 71 + 87517 = 87588
- 79 + 87509 = 87588
- 97 + 87491 = 87588
Showing the first eight; more decompositions exist.
