Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529752, here are decompositions:

3 + 31529749 = 31529752
71 + 31529681 = 31529752
83 + 31529669 = 31529752
101 + 31529651 = 31529752
281 + 31529471 = 31529752
431 + 31529321 = 31529752
479 + 31529273 = 31529752
503 + 31529249 = 31529752

Showing the first eight; more decompositions exist.
