Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78412, here are decompositions:
- 11 + 78401 = 78412
- 71 + 78341 = 78412
- 101 + 78311 = 78412
- 179 + 78233 = 78412
- 233 + 78179 = 78412
- 239 + 78173 = 78412
- 311 + 78101 = 78412
- 353 + 78059 = 78412
Showing the first eight; more decompositions exist.
