Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500246, here are decompositions:

53 + 31500193 = 31500246
59 + 31500187 = 31500246
97 + 31500149 = 31500246
139 + 31500107 = 31500246
163 + 31500083 = 31500246
199 + 31500047 = 31500246
223 + 31500023 = 31500246
229 + 31500017 = 31500246

Showing the first eight; more decompositions exist.
