Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473276, here are decompositions:

13 + 31473263 = 31473276
59 + 31473217 = 31473276
67 + 31473209 = 31473276
73 + 31473203 = 31473276
89 + 31473187 = 31473276
103 + 31473173 = 31473276
113 + 31473163 = 31473276
167 + 31473109 = 31473276

Showing the first eight; more decompositions exist.
