Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485546, here are decompositions:

5 + 31485541 = 31485546
13 + 31485533 = 31485546
73 + 31485473 = 31485546
97 + 31485449 = 31485546
139 + 31485407 = 31485546
149 + 31485397 = 31485546
163 + 31485383 = 31485546
167 + 31485379 = 31485546

Showing the first eight; more decompositions exist.
