Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573954, here are decompositions:

23 + 31573931 = 31573954
101 + 31573853 = 31573954
107 + 31573847 = 31573954
131 + 31573823 = 31573954
197 + 31573757 = 31573954
257 + 31573697 = 31573954
311 + 31573643 = 31573954
383 + 31573571 = 31573954

Showing the first eight; more decompositions exist.
