Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485934, here are decompositions:

3 + 31485931 = 31485934
17 + 31485917 = 31485934
41 + 31485893 = 31485934
101 + 31485833 = 31485934
131 + 31485803 = 31485934
167 + 31485767 = 31485934
191 + 31485743 = 31485934
197 + 31485737 = 31485934

Showing the first eight; more decompositions exist.
