Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484044, here are decompositions:

131 + 31483913 = 31484044
167 + 31483877 = 31484044
173 + 31483871 = 31484044
311 + 31483733 = 31484044
353 + 31483691 = 31484044
461 + 31483583 = 31484044
467 + 31483577 = 31484044
491 + 31483553 = 31484044

Showing the first eight; more decompositions exist.
