Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485598, here are decompositions:

101 + 31485497 = 31485598
149 + 31485449 = 31485598
167 + 31485431 = 31485598
191 + 31485407 = 31485598
197 + 31485401 = 31485598
239 + 31485359 = 31485598
257 + 31485341 = 31485598
401 + 31485197 = 31485598

Showing the first eight; more decompositions exist.
