Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529068, here are decompositions:

71 + 31528997 = 31529068
101 + 31528967 = 31529068
227 + 31528841 = 31529068
257 + 31528811 = 31529068
317 + 31528751 = 31529068
509 + 31528559 = 31529068
521 + 31528547 = 31529068
569 + 31528499 = 31529068

Showing the first eight; more decompositions exist.
