Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78290, here are decompositions:
- 7 + 78283 = 78290
- 13 + 78277 = 78290
- 31 + 78259 = 78290
- 61 + 78229 = 78290
- 97 + 78193 = 78290
- 127 + 78163 = 78290
- 151 + 78139 = 78290
- 211 + 78079 = 78290
Showing the first eight; more decompositions exist.
