Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542174, here are decompositions:

11 + 31542163 = 31542174
61 + 31542113 = 31542174
71 + 31542103 = 31542174
107 + 31542067 = 31542174
137 + 31542037 = 31542174
151 + 31542023 = 31542174
163 + 31542011 = 31542174
173 + 31542001 = 31542174

Showing the first eight; more decompositions exist.
