Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500244, here are decompositions:

23 + 31500221 = 31500244
47 + 31500197 = 31500244
131 + 31500113 = 31500244
137 + 31500107 = 31500244
197 + 31500047 = 31500244
227 + 31500017 = 31500244
311 + 31499933 = 31500244
401 + 31499843 = 31500244

Showing the first eight; more decompositions exist.
