Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183908, here are decompositions:
- 31 + 183877 = 183908
- 37 + 183871 = 183908
- 79 + 183829 = 183908
- 199 + 183709 = 183908
- 211 + 183697 = 183908
- 271 + 183637 = 183908
- 331 + 183577 = 183908
- 337 + 183571 = 183908
Showing the first eight; more decompositions exist.
