Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573176, here are decompositions:

13 + 31573163 = 31573176
23 + 31573153 = 31573176
43 + 31573133 = 31573176
53 + 31573123 = 31573176
67 + 31573109 = 31573176
73 + 31573103 = 31573176
83 + 31573093 = 31573176
139 + 31573037 = 31573176

Showing the first eight; more decompositions exist.
