Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537038, here are decompositions:

11 + 31537027 = 31537038
37 + 31537001 = 31537038
47 + 31536991 = 31537038
79 + 31536959 = 31537038
101 + 31536937 = 31537038
167 + 31536871 = 31537038
191 + 31536847 = 31537038
307 + 31536731 = 31537038

Showing the first eight; more decompositions exist.
