Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579176, here are decompositions:

37 + 31579139 = 31579176
43 + 31579133 = 31579176
47 + 31579129 = 31579176
67 + 31579109 = 31579176
73 + 31579103 = 31579176
89 + 31579087 = 31579176
103 + 31579073 = 31579176
137 + 31579039 = 31579176

Showing the first eight; more decompositions exist.
