Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461492, here are decompositions:

5 + 31461487 = 31461492
11 + 31461481 = 31461492
79 + 31461413 = 31461492
89 + 31461403 = 31461492
131 + 31461361 = 31461492
149 + 31461343 = 31461492
151 + 31461341 = 31461492
191 + 31461301 = 31461492

Showing the first eight; more decompositions exist.
