Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574910, here are decompositions:

19 + 31574891 = 31574910
23 + 31574887 = 31574910
47 + 31574863 = 31574910
61 + 31574849 = 31574910
89 + 31574821 = 31574910
97 + 31574813 = 31574910
131 + 31574779 = 31574910
137 + 31574773 = 31574910

Showing the first eight; more decompositions exist.
