Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454850, here are decompositions:

13 + 31454837 = 31454850
23 + 31454827 = 31454850
41 + 31454809 = 31454850
67 + 31454783 = 31454850
109 + 31454741 = 31454850
113 + 31454737 = 31454850
149 + 31454701 = 31454850
181 + 31454669 = 31454850

Showing the first eight; more decompositions exist.
