Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567582, here are decompositions:

23 + 31567559 = 31567582
29 + 31567553 = 31567582
71 + 31567511 = 31567582
131 + 31567451 = 31567582
269 + 31567313 = 31567582
311 + 31567271 = 31567582
491 + 31567091 = 31567582
719 + 31566863 = 31567582

Showing the first eight; more decompositions exist.
