Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78078, here are decompositions:
- 19 + 78059 = 78078
- 29 + 78049 = 78078
- 37 + 78041 = 78078
- 47 + 78031 = 78078
- 61 + 78017 = 78078
- 71 + 78007 = 78078
- 79 + 77999 = 78078
- 101 + 77977 = 78078
Showing the first eight; more decompositions exist.
