Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499626, here are decompositions:

5 + 31499621 = 31499626
89 + 31499537 = 31499626
167 + 31499459 = 31499626
227 + 31499399 = 31499626
239 + 31499387 = 31499626
317 + 31499309 = 31499626
359 + 31499267 = 31499626
443 + 31499183 = 31499626

Showing the first eight; more decompositions exist.
