Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45818, here are decompositions:

61 + 45757 = 45818
67 + 45751 = 45818
127 + 45691 = 45818
151 + 45667 = 45818
229 + 45589 = 45818
277 + 45541 = 45818
337 + 45481 = 45818
379 + 45439 = 45818

Showing the first eight; more decompositions exist.
