Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145182, here are decompositions:

5 + 145177 = 145182
43 + 145139 = 145182
61 + 145121 = 145182
73 + 145109 = 145182
113 + 145069 = 145182
139 + 145043 = 145182
151 + 145031 = 145182
173 + 145009 = 145182

Showing the first eight; more decompositions exist.
