Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45312, here are decompositions:
- 5 + 45307 = 45312
- 19 + 45293 = 45312
- 23 + 45289 = 45312
- 31 + 45281 = 45312
- 53 + 45259 = 45312
- 79 + 45233 = 45312
- 131 + 45181 = 45312
- 151 + 45161 = 45312
Showing the first eight; more decompositions exist.
