Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579654, here are decompositions:

3 + 31579651 = 31579654
11 + 31579643 = 31579654
173 + 31579481 = 31579654
311 + 31579343 = 31579654
461 + 31579193 = 31579654
467 + 31579187 = 31579654
521 + 31579133 = 31579654
563 + 31579091 = 31579654

Showing the first eight; more decompositions exist.
