Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532650, here are decompositions:

11 + 31532639 = 31532650
53 + 31532597 = 31532650
173 + 31532477 = 31532650
311 + 31532339 = 31532650
389 + 31532261 = 31532650
431 + 31532219 = 31532650
509 + 31532141 = 31532650
587 + 31532063 = 31532650

Showing the first eight; more decompositions exist.
