Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523056, here are decompositions:

3 + 31523053 = 31523056
29 + 31523027 = 31523056
53 + 31523003 = 31523056
167 + 31522889 = 31523056
233 + 31522823 = 31523056
443 + 31522613 = 31523056
503 + 31522553 = 31523056
563 + 31522493 = 31523056

Showing the first eight; more decompositions exist.
