Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87636, here are decompositions:
- 5 + 87631 = 87636
- 7 + 87629 = 87636
- 13 + 87623 = 87636
- 23 + 87613 = 87636
- 47 + 87589 = 87636
- 53 + 87583 = 87636
- 79 + 87557 = 87636
- 83 + 87553 = 87636
Showing the first eight; more decompositions exist.
