Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492074, here are decompositions:

7 + 31492067 = 31492074
13 + 31492061 = 31492074
23 + 31492051 = 31492074
41 + 31492033 = 31492074
43 + 31492031 = 31492074
157 + 31491917 = 31492074
181 + 31491893 = 31492074
193 + 31491881 = 31492074

Showing the first eight; more decompositions exist.
