Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623364, here are decompositions:

107 + 31623257 = 31623364
191 + 31623173 = 31623364
197 + 31623167 = 31623364
251 + 31623113 = 31623364
317 + 31623047 = 31623364
431 + 31622933 = 31623364
587 + 31622777 = 31623364
677 + 31622687 = 31623364

Showing the first eight; more decompositions exist.
