Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492914, here are decompositions:

7 + 31492907 = 31492914
67 + 31492847 = 31492914
73 + 31492841 = 31492914
113 + 31492801 = 31492914
137 + 31492777 = 31492914
157 + 31492757 = 31492914
163 + 31492751 = 31492914
223 + 31492691 = 31492914

Showing the first eight; more decompositions exist.
