Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45008, here are decompositions:

37 + 44971 = 45008
157 + 44851 = 45008
199 + 44809 = 45008
211 + 44797 = 45008
307 + 44701 = 45008
367 + 44641 = 45008
421 + 44587 = 45008
619 + 44389 = 45008

Showing the first eight; more decompositions exist.
