Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78434, here are decompositions:
- 7 + 78427 = 78434
- 67 + 78367 = 78434
- 127 + 78307 = 78434
- 151 + 78283 = 78434
- 157 + 78277 = 78434
- 193 + 78241 = 78434
- 241 + 78193 = 78434
- 271 + 78163 = 78434
Showing the first eight; more decompositions exist.
