Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579246, here are decompositions:

53 + 31579193 = 31579246
59 + 31579187 = 31579246
107 + 31579139 = 31579246
113 + 31579133 = 31579246
137 + 31579109 = 31579246
173 + 31579073 = 31579246
317 + 31578929 = 31579246
359 + 31578887 = 31579246

Showing the first eight; more decompositions exist.
