Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87956, here are decompositions:
- 13 + 87943 = 87956
- 79 + 87877 = 87956
- 103 + 87853 = 87956
- 163 + 87793 = 87956
- 277 + 87679 = 87956
- 307 + 87649 = 87956
- 313 + 87643 = 87956
- 367 + 87589 = 87956
Showing the first eight; more decompositions exist.
