Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517624, here are decompositions:

7 + 31517617 = 31517624
37 + 31517587 = 31517624
67 + 31517557 = 31517624
97 + 31517527 = 31517624
157 + 31517467 = 31517624
211 + 31517413 = 31517624
613 + 31517011 = 31517624
631 + 31516993 = 31517624

Showing the first eight; more decompositions exist.
