Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486222, here are decompositions:

59 + 31486163 = 31486222
101 + 31486121 = 31486222
113 + 31486109 = 31486222
263 + 31485959 = 31486222
269 + 31485953 = 31486222
281 + 31485941 = 31486222
389 + 31485833 = 31486222
419 + 31485803 = 31486222

Showing the first eight; more decompositions exist.
