Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524586, here are decompositions:

17 + 31524569 = 31524586
53 + 31524533 = 31524586
167 + 31524419 = 31524586
293 + 31524293 = 31524586
389 + 31524197 = 31524586
419 + 31524167 = 31524586
479 + 31524107 = 31524586
563 + 31524023 = 31524586

Showing the first eight; more decompositions exist.
