Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472826, here are decompositions:

13 + 31472813 = 31472826
19 + 31472807 = 31472826
53 + 31472773 = 31472826
103 + 31472723 = 31472826
127 + 31472699 = 31472826
157 + 31472669 = 31472826
163 + 31472663 = 31472826
193 + 31472633 = 31472826

Showing the first eight; more decompositions exist.
