Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473024, here are decompositions:

41 + 31472983 = 31473024
61 + 31472963 = 31473024
97 + 31472927 = 31473024
137 + 31472887 = 31473024
157 + 31472867 = 31473024
173 + 31472851 = 31473024
197 + 31472827 = 31473024
211 + 31472813 = 31473024

Showing the first eight; more decompositions exist.
