Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78102, here are decompositions:
- 23 + 78079 = 78102
- 43 + 78059 = 78102
- 53 + 78049 = 78102
- 61 + 78041 = 78102
- 71 + 78031 = 78102
- 103 + 77999 = 78102
- 151 + 77951 = 78102
- 173 + 77929 = 78102
Showing the first eight; more decompositions exist.
