Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461444, here are decompositions:

17 + 31461427 = 31461444
31 + 31461413 = 31461444
41 + 31461403 = 31461444
83 + 31461361 = 31461444
101 + 31461343 = 31461444
103 + 31461341 = 31461444
151 + 31461293 = 31461444
163 + 31461281 = 31461444

Showing the first eight; more decompositions exist.
