Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532044, here are decompositions:

23 + 31532021 = 31532044
41 + 31532003 = 31532044
113 + 31531931 = 31532044
227 + 31531817 = 31532044
293 + 31531751 = 31532044
317 + 31531727 = 31532044
521 + 31531523 = 31532044
587 + 31531457 = 31532044

Showing the first eight; more decompositions exist.
