Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579462, here are decompositions:

269 + 31579193 = 31579462
281 + 31579181 = 31579462
353 + 31579109 = 31579462
359 + 31579103 = 31579462
389 + 31579073 = 31579462
641 + 31578821 = 31579462
743 + 31578719 = 31579462
839 + 31578623 = 31579462

Showing the first eight; more decompositions exist.
