Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574826, here are decompositions:

5 + 31574821 = 31574826
13 + 31574813 = 31574826
47 + 31574779 = 31574826
53 + 31574773 = 31574826
79 + 31574747 = 31574826
103 + 31574723 = 31574826
137 + 31574689 = 31574826
139 + 31574687 = 31574826

Showing the first eight; more decompositions exist.
