Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523094, here are decompositions:

13 + 31523081 = 31523094
41 + 31523053 = 31523094
67 + 31523027 = 31523094
73 + 31523021 = 31523094
107 + 31522987 = 31523094
157 + 31522937 = 31523094
193 + 31522901 = 31523094
271 + 31522823 = 31523094

Showing the first eight; more decompositions exist.
