Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87650, here are decompositions:
- 7 + 87643 = 87650
- 19 + 87631 = 87650
- 37 + 87613 = 87650
- 61 + 87589 = 87650
- 67 + 87583 = 87650
- 97 + 87553 = 87650
- 103 + 87547 = 87650
- 109 + 87541 = 87650
Showing the first eight; more decompositions exist.
