Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529488, here are decompositions:

17 + 31529471 = 31529488
41 + 31529447 = 31529488
167 + 31529321 = 31529488
239 + 31529249 = 31529488
269 + 31529219 = 31529488
401 + 31529087 = 31529488
491 + 31528997 = 31529488
521 + 31528967 = 31529488

Showing the first eight; more decompositions exist.
