Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45812, here are decompositions:
- 61 + 45751 = 45812
- 139 + 45673 = 45812
- 181 + 45631 = 45812
- 199 + 45613 = 45812
- 223 + 45589 = 45812
- 271 + 45541 = 45812
- 331 + 45481 = 45812
- 373 + 45439 = 45812
Showing the first eight; more decompositions exist.
