Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546722, here are decompositions:

5 + 31546717 = 31546722
13 + 31546709 = 31546722
59 + 31546663 = 31546722
61 + 31546661 = 31546722
89 + 31546633 = 31546722
101 + 31546621 = 31546722
131 + 31546591 = 31546722
139 + 31546583 = 31546722

Showing the first eight; more decompositions exist.
