Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579602, here are decompositions:

59 + 31579543 = 31579602
83 + 31579519 = 31579602
149 + 31579453 = 31579602
191 + 31579411 = 31579602
251 + 31579351 = 31579602
281 + 31579321 = 31579602
311 + 31579291 = 31579602
389 + 31579213 = 31579602

Showing the first eight; more decompositions exist.
