Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484074, here are decompositions:

3 + 31484071 = 31484074
5 + 31484069 = 31484074
191 + 31483883 = 31484074
197 + 31483877 = 31484074
233 + 31483841 = 31484074
383 + 31483691 = 31484074
491 + 31483583 = 31484074
521 + 31483553 = 31484074

Showing the first eight; more decompositions exist.
