Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579606, here are decompositions:

137 + 31579469 = 31579606
263 + 31579343 = 31579606
419 + 31579187 = 31579606
467 + 31579139 = 31579606
479 + 31579127 = 31579606
503 + 31579103 = 31579606
659 + 31578947 = 31579606
677 + 31578929 = 31579606

Showing the first eight; more decompositions exist.
