Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529526, here are decompositions:

5 + 31529521 = 31529526
19 + 31529507 = 31529526
47 + 31529479 = 31529526
79 + 31529447 = 31529526
113 + 31529413 = 31529526
167 + 31529359 = 31529526
173 + 31529353 = 31529526
179 + 31529347 = 31529526

Showing the first eight; more decompositions exist.
