Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460464, here are decompositions:

23 + 31460441 = 31460464
173 + 31460291 = 31460464
197 + 31460267 = 31460464
401 + 31460063 = 31460464
617 + 31459847 = 31460464
797 + 31459667 = 31460464
911 + 31459553 = 31460464
947 + 31459517 = 31460464

Showing the first eight; more decompositions exist.
