Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532188, here are decompositions:

47 + 31532141 = 31532188
71 + 31532117 = 31532188
167 + 31532021 = 31532188
257 + 31531931 = 31532188
461 + 31531727 = 31532188
509 + 31531679 = 31532188
521 + 31531667 = 31532188
887 + 31531301 = 31532188

Showing the first eight; more decompositions exist.
