Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573462, here are decompositions:

71 + 31573391 = 31573462
101 + 31573361 = 31573462
251 + 31573211 = 31573462
311 + 31573151 = 31573462
353 + 31573109 = 31573462
359 + 31573103 = 31573462
491 + 31572971 = 31573462
521 + 31572941 = 31573462

Showing the first eight; more decompositions exist.
