Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479492, here are decompositions:

53 + 31479439 = 31479492
71 + 31479421 = 31479492
73 + 31479419 = 31479492
193 + 31479299 = 31479492
223 + 31479269 = 31479492
241 + 31479251 = 31479492
251 + 31479241 = 31479492
409 + 31479083 = 31479492

Showing the first eight; more decompositions exist.
