Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472524, here are decompositions:

23 + 31472501 = 31472524
173 + 31472351 = 31472524
233 + 31472291 = 31472524
263 + 31472261 = 31472524
401 + 31472123 = 31472524
521 + 31472003 = 31472524
557 + 31471967 = 31472524
617 + 31471907 = 31472524

Showing the first eight; more decompositions exist.
