Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573070, here are decompositions:

13 + 31573057 = 31573070
43 + 31573027 = 31573070
127 + 31572943 = 31573070
229 + 31572841 = 31573070
307 + 31572763 = 31573070
337 + 31572733 = 31573070
421 + 31572649 = 31573070
433 + 31572637 = 31573070

Showing the first eight; more decompositions exist.
