Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8378, here are decompositions:
- 61 + 8317 = 8378
- 67 + 8311 = 8378
- 109 + 8269 = 8378
- 157 + 8221 = 8378
- 199 + 8179 = 8378
- 211 + 8167 = 8378
- 277 + 8101 = 8378
- 367 + 8011 = 8378
Showing the first eight; more decompositions exist.
