Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500136, here are decompositions:

23 + 31500113 = 31500136
29 + 31500107 = 31500136
53 + 31500083 = 31500136
89 + 31500047 = 31500136
113 + 31500023 = 31500136
197 + 31499939 = 31500136
293 + 31499843 = 31500136
599 + 31499537 = 31500136

Showing the first eight; more decompositions exist.
