Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87716, here are decompositions:
- 19 + 87697 = 87716
- 37 + 87679 = 87716
- 67 + 87649 = 87716
- 73 + 87643 = 87716
- 103 + 87613 = 87716
- 127 + 87589 = 87716
- 157 + 87559 = 87716
- 163 + 87553 = 87716
Showing the first eight; more decompositions exist.
