Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145674, here are decompositions:

13 + 145661 = 145674
31 + 145643 = 145674
37 + 145637 = 145674
41 + 145633 = 145674
71 + 145603 = 145674
73 + 145601 = 145674
97 + 145577 = 145674
127 + 145547 = 145674

Showing the first eight; more decompositions exist.
