Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473030, here are decompositions:

47 + 31472983 = 31473030
67 + 31472963 = 31473030
101 + 31472929 = 31473030
103 + 31472927 = 31473030
139 + 31472891 = 31473030
151 + 31472879 = 31473030
163 + 31472867 = 31473030
179 + 31472851 = 31473030

Showing the first eight; more decompositions exist.
