Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45500, here are decompositions:

3 + 45497 = 45500
19 + 45481 = 45500
61 + 45439 = 45500
67 + 45433 = 45500
73 + 45427 = 45500
97 + 45403 = 45500
139 + 45361 = 45500
157 + 45343 = 45500

Showing the first eight; more decompositions exist.
