Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529544, here are decompositions:

5 + 31529539 = 31529544
23 + 31529521 = 31529544
37 + 31529507 = 31529544
73 + 31529471 = 31529544
97 + 31529447 = 31529544
113 + 31529431 = 31529544
131 + 31529413 = 31529544
191 + 31529353 = 31529544

Showing the first eight; more decompositions exist.
