Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523706, here are decompositions:

37 + 31523669 = 31523706
47 + 31523659 = 31523706
59 + 31523647 = 31523706
73 + 31523633 = 31523706
107 + 31523599 = 31523706
127 + 31523579 = 31523706
167 + 31523539 = 31523706
229 + 31523477 = 31523706

Showing the first eight; more decompositions exist.
