Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453566, here are decompositions:

37 + 31453529 = 31453566
43 + 31453523 = 31453566
59 + 31453507 = 31453566
83 + 31453483 = 31453566
103 + 31453463 = 31453566
139 + 31453427 = 31453566
173 + 31453393 = 31453566
233 + 31453333 = 31453566

Showing the first eight; more decompositions exist.
