Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51464, here are decompositions:
- 3 + 51461 = 51464
- 37 + 51427 = 51464
- 43 + 51421 = 51464
- 103 + 51361 = 51464
- 157 + 51307 = 51464
- 181 + 51283 = 51464
- 223 + 51241 = 51464
- 271 + 51193 = 51464
Showing the first eight; more decompositions exist.
