Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78086, here are decompositions:
- 7 + 78079 = 78086
- 37 + 78049 = 78086
- 79 + 78007 = 78086
- 103 + 77983 = 78086
- 109 + 77977 = 78086
- 157 + 77929 = 78086
- 193 + 77893 = 78086
- 223 + 77863 = 78086
Showing the first eight; more decompositions exist.
