Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473042, here are decompositions:

5 + 31473037 = 31473042
11 + 31473031 = 31473042
59 + 31472983 = 31473042
79 + 31472963 = 31473042
113 + 31472929 = 31473042
151 + 31472891 = 31473042
163 + 31472879 = 31473042
191 + 31472851 = 31473042

Showing the first eight; more decompositions exist.
