Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532284, here are decompositions:

5 + 31532279 = 31532284
23 + 31532261 = 31532284
167 + 31532117 = 31532284
263 + 31532021 = 31532284
281 + 31532003 = 31532284
317 + 31531967 = 31532284
353 + 31531931 = 31532284
401 + 31531883 = 31532284

Showing the first eight; more decompositions exist.
