Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484038, here are decompositions:

59 + 31483979 = 31484038
149 + 31483889 = 31484038
167 + 31483871 = 31484038
197 + 31483841 = 31484038
239 + 31483799 = 31484038
347 + 31483691 = 31484038
389 + 31483649 = 31484038
461 + 31483577 = 31484038

Showing the first eight; more decompositions exist.
