Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529554, here are decompositions:

3 + 31529551 = 31529554
47 + 31529507 = 31529554
83 + 31529471 = 31529554
107 + 31529447 = 31529554
233 + 31529321 = 31529554
281 + 31529273 = 31529554
311 + 31529243 = 31529554
467 + 31529087 = 31529554

Showing the first eight; more decompositions exist.
