Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582772, here are decompositions:

43 + 31582729 = 31582772
139 + 31582633 = 31582772
163 + 31582609 = 31582772
241 + 31582531 = 31582772
283 + 31582489 = 31582772
373 + 31582399 = 31582772
439 + 31582333 = 31582772
523 + 31582249 = 31582772

Showing the first eight; more decompositions exist.
