Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573012, here are decompositions:

5 + 31573007 = 31573012
41 + 31572971 = 31573012
71 + 31572941 = 31573012
131 + 31572881 = 31573012
281 + 31572731 = 31573012
461 + 31572551 = 31573012
479 + 31572533 = 31573012
491 + 31572521 = 31573012

Showing the first eight; more decompositions exist.
