Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45216, here are decompositions:
- 19 + 45197 = 45216
- 37 + 45179 = 45216
- 79 + 45137 = 45216
- 89 + 45127 = 45216
- 97 + 45119 = 45216
- 139 + 45077 = 45216
- 163 + 45053 = 45216
- 229 + 44987 = 45216
Showing the first eight; more decompositions exist.
