Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573926, here are decompositions:

67 + 31573859 = 31573926
73 + 31573853 = 31573926
79 + 31573847 = 31573926
103 + 31573823 = 31573926
107 + 31573819 = 31573926
173 + 31573753 = 31573926
179 + 31573747 = 31573926
229 + 31573697 = 31573926

Showing the first eight; more decompositions exist.
