Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579692, here are decompositions:

31 + 31579661 = 31579692
41 + 31579651 = 31579692
59 + 31579633 = 31579692
73 + 31579619 = 31579692
149 + 31579543 = 31579692
173 + 31579519 = 31579692
181 + 31579511 = 31579692
211 + 31579481 = 31579692

Showing the first eight; more decompositions exist.
