Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99378, here are decompositions:
- 7 + 99371 = 99378
- 11 + 99367 = 99378
- 29 + 99349 = 99378
- 31 + 99347 = 99378
- 61 + 99317 = 99378
- 89 + 99289 = 99378
- 101 + 99277 = 99378
- 127 + 99251 = 99378
Showing the first eight; more decompositions exist.
