Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485044, here are decompositions:

13 + 31485031 = 31485044
43 + 31485001 = 31485044
103 + 31484941 = 31485044
181 + 31484863 = 31485044
223 + 31484821 = 31485044
397 + 31484647 = 31485044
541 + 31484503 = 31485044
631 + 31484413 = 31485044

Showing the first eight; more decompositions exist.
