Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483424, here are decompositions:

73 + 31483351 = 31483424
97 + 31483327 = 31483424
163 + 31483261 = 31483424
211 + 31483213 = 31483424
307 + 31483117 = 31483424
331 + 31483093 = 31483424
337 + 31483087 = 31483424
373 + 31483051 = 31483424

Showing the first eight; more decompositions exist.
