Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500354, here are decompositions:

73 + 31500281 = 31500354
157 + 31500197 = 31500354
167 + 31500187 = 31500354
241 + 31500113 = 31500354
271 + 31500083 = 31500354
307 + 31500047 = 31500354
331 + 31500023 = 31500354
337 + 31500017 = 31500354

Showing the first eight; more decompositions exist.
