Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573054, here are decompositions:

17 + 31573037 = 31573054
47 + 31573007 = 31573054
83 + 31572971 = 31573054
113 + 31572941 = 31573054
173 + 31572881 = 31573054
503 + 31572551 = 31573054
521 + 31572533 = 31573054
593 + 31572461 = 31573054

Showing the first eight; more decompositions exist.
