Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579714, here are decompositions:

11 + 31579703 = 31579714
53 + 31579661 = 31579714
71 + 31579643 = 31579714
233 + 31579481 = 31579714
521 + 31579193 = 31579714
587 + 31579127 = 31579714
641 + 31579073 = 31579714
827 + 31578887 = 31579714

Showing the first eight; more decompositions exist.
