Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51222, here are decompositions:
- 5 + 51217 = 51222
- 19 + 51203 = 51222
- 23 + 51199 = 51222
- 29 + 51193 = 51222
- 53 + 51169 = 51222
- 71 + 51151 = 51222
- 89 + 51133 = 51222
- 113 + 51109 = 51222
Showing the first eight; more decompositions exist.
