Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78372, here are decompositions:
- 5 + 78367 = 78372
- 31 + 78341 = 78372
- 61 + 78311 = 78372
- 71 + 78301 = 78372
- 89 + 78283 = 78372
- 113 + 78259 = 78372
- 131 + 78241 = 78372
- 139 + 78233 = 78372
Showing the first eight; more decompositions exist.
