Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619042, here are decompositions:

43 + 31618999 = 31619042
61 + 31618981 = 31619042
151 + 31618891 = 31619042
163 + 31618879 = 31619042
193 + 31618849 = 31619042
223 + 31618819 = 31619042
271 + 31618771 = 31619042
331 + 31618711 = 31619042

Showing the first eight; more decompositions exist.
