Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483184, here are decompositions:

67 + 31483117 = 31483184
97 + 31483087 = 31483184
181 + 31483003 = 31483184
193 + 31482991 = 31483184
211 + 31482973 = 31483184
277 + 31482907 = 31483184
541 + 31482643 = 31483184
571 + 31482613 = 31483184

Showing the first eight; more decompositions exist.
