Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529574, here are decompositions:

7 + 31529567 = 31529574
17 + 31529557 = 31529574
23 + 31529551 = 31529574
53 + 31529521 = 31529574
67 + 31529507 = 31529574
103 + 31529471 = 31529574
127 + 31529447 = 31529574
227 + 31529347 = 31529574

Showing the first eight; more decompositions exist.
