Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532338, here are decompositions:

59 + 31532279 = 31532338
197 + 31532141 = 31532338
317 + 31532021 = 31532338
521 + 31531817 = 31532338
587 + 31531751 = 31532338
659 + 31531679 = 31532338
881 + 31531457 = 31532338
1259 + 31531079 = 31532338

Showing the first eight; more decompositions exist.
