Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51204, here are decompositions:
- 5 + 51199 = 51204
- 7 + 51197 = 51204
- 11 + 51193 = 51204
- 47 + 51157 = 51204
- 53 + 51151 = 51204
- 67 + 51137 = 51204
- 71 + 51133 = 51204
- 73 + 51131 = 51204
Showing the first eight; more decompositions exist.
