Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494610, here are decompositions:

29 + 31494581 = 31494610
101 + 31494509 = 31494610
107 + 31494503 = 31494610
113 + 31494497 = 31494610
131 + 31494479 = 31494610
167 + 31494443 = 31494610
179 + 31494431 = 31494610
263 + 31494347 = 31494610

Showing the first eight; more decompositions exist.
