Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537010, here are decompositions:

7 + 31537003 = 31537010
19 + 31536991 = 31537010
67 + 31536943 = 31537010
73 + 31536937 = 31537010
139 + 31536871 = 31537010
163 + 31536847 = 31537010
181 + 31536829 = 31537010
277 + 31536733 = 31537010

Showing the first eight; more decompositions exist.
