Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529494, here are decompositions:

23 + 31529471 = 31529494
47 + 31529447 = 31529494
173 + 31529321 = 31529494
251 + 31529243 = 31529494
281 + 31529213 = 31529494
641 + 31528853 = 31529494
653 + 31528841 = 31529494
683 + 31528811 = 31529494

Showing the first eight; more decompositions exist.
