Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517652, here are decompositions:

11 + 31517641 = 31517652
13 + 31517639 = 31517652
73 + 31517579 = 31517652
79 + 31517573 = 31517652
109 + 31517543 = 31517652
151 + 31517501 = 31517652
211 + 31517441 = 31517652
239 + 31517413 = 31517652

Showing the first eight; more decompositions exist.
