Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45542, here are decompositions:

19 + 45523 = 45542
61 + 45481 = 45542
103 + 45439 = 45542
109 + 45433 = 45542
139 + 45403 = 45542
181 + 45361 = 45542
199 + 45343 = 45542
223 + 45319 = 45542

Showing the first eight; more decompositions exist.
