Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45380, here are decompositions:

3 + 45377 = 45380
19 + 45361 = 45380
37 + 45343 = 45380
43 + 45337 = 45380
61 + 45319 = 45380
73 + 45307 = 45380
199 + 45181 = 45380
241 + 45139 = 45380

Showing the first eight; more decompositions exist.
