Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529062, here are decompositions:

239 + 31528823 = 31529062
251 + 31528811 = 31529062
311 + 31528751 = 31529062
449 + 31528613 = 31529062
503 + 31528559 = 31529062
563 + 31528499 = 31529062
821 + 31528241 = 31529062
911 + 31528151 = 31529062

Showing the first eight; more decompositions exist.
