Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84378, here are decompositions:
- 29 + 84349 = 84378
- 31 + 84347 = 84378
- 59 + 84319 = 84378
- 61 + 84317 = 84378
- 71 + 84307 = 84378
- 79 + 84299 = 84378
- 131 + 84247 = 84378
- 139 + 84239 = 84378
Showing the first eight; more decompositions exist.
