Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574106, here are decompositions:

7 + 31574099 = 31574106
13 + 31574093 = 31574106
59 + 31574047 = 31574106
107 + 31573999 = 31574106
139 + 31573967 = 31574106
149 + 31573957 = 31574106
283 + 31573823 = 31574106
313 + 31573793 = 31574106

Showing the first eight; more decompositions exist.
