Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579594, here are decompositions:

83 + 31579511 = 31579594
113 + 31579481 = 31579594
251 + 31579343 = 31579594
317 + 31579277 = 31579594
401 + 31579193 = 31579594
461 + 31579133 = 31579594
467 + 31579127 = 31579594
491 + 31579103 = 31579594

Showing the first eight; more decompositions exist.
