Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51008, here are decompositions:
- 7 + 51001 = 51008
- 19 + 50989 = 51008
- 37 + 50971 = 51008
- 79 + 50929 = 51008
- 151 + 50857 = 51008
- 241 + 50767 = 51008
- 337 + 50671 = 51008
- 409 + 50599 = 51008
Showing the first eight; more decompositions exist.
