Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76986, here are decompositions:
- 23 + 76963 = 76986
- 37 + 76949 = 76986
- 43 + 76943 = 76986
- 67 + 76919 = 76986
- 73 + 76913 = 76986
- 79 + 76907 = 76986
- 103 + 76883 = 76986
- 113 + 76873 = 76986
Showing the first eight; more decompositions exist.
