Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582624, here are decompositions:

11 + 31582613 = 31582624
23 + 31582601 = 31582624
71 + 31582553 = 31582624
383 + 31582241 = 31582624
431 + 31582193 = 31582624
461 + 31582163 = 31582624
503 + 31582121 = 31582624
587 + 31582037 = 31582624

Showing the first eight; more decompositions exist.
