Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532434, here are decompositions:

5 + 31532429 = 31532434
173 + 31532261 = 31532434
293 + 31532141 = 31532434
317 + 31532117 = 31532434
431 + 31532003 = 31532434
467 + 31531967 = 31532434
503 + 31531931 = 31532434
617 + 31531817 = 31532434

Showing the first eight; more decompositions exist.
