Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484042, here are decompositions:

61 + 31483981 = 31484042
181 + 31483861 = 31484042
223 + 31483819 = 31484042
241 + 31483801 = 31484042
283 + 31483759 = 31484042
379 + 31483663 = 31484042
571 + 31483471 = 31484042
613 + 31483429 = 31484042

Showing the first eight; more decompositions exist.
