Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463186, here are decompositions:

19 + 31463167 = 31463186
103 + 31463083 = 31463186
109 + 31463077 = 31463186
163 + 31463023 = 31463186
277 + 31462909 = 31463186
379 + 31462807 = 31463186
439 + 31462747 = 31463186
457 + 31462729 = 31463186

Showing the first eight; more decompositions exist.
