Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75378, here are decompositions:
- 11 + 75367 = 75378
- 31 + 75347 = 75378
- 41 + 75337 = 75378
- 71 + 75307 = 75378
- 89 + 75289 = 75378
- 101 + 75277 = 75378
- 109 + 75269 = 75378
- 139 + 75239 = 75378
Showing the first eight; more decompositions exist.
