Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486226, here are decompositions:

97 + 31486129 = 31486226
103 + 31486123 = 31486226
139 + 31486087 = 31486226
193 + 31486033 = 31486226
337 + 31485889 = 31486226
643 + 31485583 = 31486226
829 + 31485397 = 31486226
907 + 31485319 = 31486226

Showing the first eight; more decompositions exist.
