Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582546, here are decompositions:

137 + 31582409 = 31582546
227 + 31582319 = 31582546
353 + 31582193 = 31582546
383 + 31582163 = 31582546
449 + 31582097 = 31582546
503 + 31582043 = 31582546
509 + 31582037 = 31582546
563 + 31581983 = 31582546

Showing the first eight; more decompositions exist.
