Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500348, here are decompositions:

67 + 31500281 = 31500348
127 + 31500221 = 31500348
151 + 31500197 = 31500348
199 + 31500149 = 31500348
241 + 31500107 = 31500348
331 + 31500017 = 31500348
359 + 31499989 = 31500348
409 + 31499939 = 31500348

Showing the first eight; more decompositions exist.
