Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626012, here are decompositions:

31 + 31625981 = 31626012
43 + 31625969 = 31626012
59 + 31625953 = 31626012
73 + 31625939 = 31626012
101 + 31625911 = 31626012
163 + 31625849 = 31626012
191 + 31625821 = 31626012
193 + 31625819 = 31626012

Showing the first eight; more decompositions exist.
