Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532374, here are decompositions:

113 + 31532261 = 31532374
233 + 31532141 = 31532374
257 + 31532117 = 31532374
311 + 31532063 = 31532374
353 + 31532021 = 31532374
443 + 31531931 = 31532374
491 + 31531883 = 31532374
557 + 31531817 = 31532374

Showing the first eight; more decompositions exist.
