Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500336, here are decompositions:

73 + 31500263 = 31500336
139 + 31500197 = 31500336
149 + 31500187 = 31500336
223 + 31500113 = 31500336
229 + 31500107 = 31500336
313 + 31500023 = 31500336
347 + 31499989 = 31500336
397 + 31499939 = 31500336

Showing the first eight; more decompositions exist.
