Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484032, here are decompositions:

53 + 31483979 = 31484032
113 + 31483919 = 31484032
149 + 31483883 = 31484032
191 + 31483841 = 31484032
233 + 31483799 = 31484032
383 + 31483649 = 31484032
449 + 31483583 = 31484032
479 + 31483553 = 31484032

Showing the first eight; more decompositions exist.
