Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480552, here are decompositions:

23 + 31480529 = 31480552
179 + 31480373 = 31480552
263 + 31480289 = 31480552
293 + 31480259 = 31480552
449 + 31480103 = 31480552
461 + 31480091 = 31480552
491 + 31480061 = 31480552
503 + 31480049 = 31480552

Showing the first eight; more decompositions exist.
