Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546802, here are decompositions:

3 + 31546799 = 31546802
13 + 31546789 = 31546802
43 + 31546759 = 31546802
61 + 31546741 = 31546802
139 + 31546663 = 31546802
181 + 31546621 = 31546802
211 + 31546591 = 31546802
229 + 31546573 = 31546802

Showing the first eight; more decompositions exist.
