Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579334, here are decompositions:

13 + 31579321 = 31579334
43 + 31579291 = 31579334
97 + 31579237 = 31579334
331 + 31579003 = 31579334
547 + 31578787 = 31579334
571 + 31578763 = 31579334
613 + 31578721 = 31579334
643 + 31578691 = 31579334

Showing the first eight; more decompositions exist.
