Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485498, here are decompositions:

67 + 31485431 = 31485498
71 + 31485427 = 31485498
97 + 31485401 = 31485498
101 + 31485397 = 31485498
139 + 31485359 = 31485498
157 + 31485341 = 31485498
179 + 31485319 = 31485498
197 + 31485301 = 31485498

Showing the first eight; more decompositions exist.
