Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582722, here are decompositions:

43 + 31582679 = 31582722
89 + 31582633 = 31582722
109 + 31582613 = 31582722
113 + 31582609 = 31582722
163 + 31582559 = 31582722
191 + 31582531 = 31582722
233 + 31582489 = 31582722
251 + 31582471 = 31582722

Showing the first eight; more decompositions exist.
