Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579662, here are decompositions:

11 + 31579651 = 31579662
19 + 31579643 = 31579662
29 + 31579633 = 31579662
43 + 31579619 = 31579662
151 + 31579511 = 31579662
181 + 31579481 = 31579662
193 + 31579469 = 31579662
251 + 31579411 = 31579662

Showing the first eight; more decompositions exist.
