Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480626, here are decompositions:

5 + 31480621 = 31480626
97 + 31480529 = 31480626
193 + 31480433 = 31480626
257 + 31480369 = 31480626
277 + 31480349 = 31480626
337 + 31480289 = 31480626
367 + 31480259 = 31480626
509 + 31480117 = 31480626

Showing the first eight; more decompositions exist.
