Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532812, here are decompositions:

173 + 31532639 = 31532812
239 + 31532573 = 31532812
383 + 31532429 = 31532812
593 + 31532219 = 31532812
809 + 31532003 = 31532812
881 + 31531931 = 31532812
929 + 31531883 = 31532812
1061 + 31531751 = 31532812

Showing the first eight; more decompositions exist.
