Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573194, here are decompositions:

5 + 31573189 = 31573194
31 + 31573163 = 31573194
41 + 31573153 = 31573194
43 + 31573151 = 31573194
61 + 31573133 = 31573194
67 + 31573127 = 31573194
71 + 31573123 = 31573194
83 + 31573111 = 31573194

Showing the first eight; more decompositions exist.
