Goldbach decomposition

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.
