Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486084, here are decompositions:

131 + 31485953 = 31486084
167 + 31485917 = 31486084
191 + 31485893 = 31486084
251 + 31485833 = 31486084
281 + 31485803 = 31486084
293 + 31485791 = 31486084
317 + 31485767 = 31486084
347 + 31485737 = 31486084

Showing the first eight; more decompositions exist.
