Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453524, here are decompositions:

17 + 31453507 = 31453524
23 + 31453501 = 31453524
41 + 31453483 = 31453524
61 + 31453463 = 31453524
97 + 31453427 = 31453524
103 + 31453421 = 31453524
131 + 31453393 = 31453524
163 + 31453361 = 31453524

Showing the first eight; more decompositions exist.
