Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479462, here are decompositions:

5 + 31479457 = 31479462
23 + 31479439 = 31479462
41 + 31479421 = 31479462
43 + 31479419 = 31479462
163 + 31479299 = 31479462
173 + 31479289 = 31479462
191 + 31479271 = 31479462
193 + 31479269 = 31479462

Showing the first eight; more decompositions exist.
