Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473104, here are decompositions:

37 + 31473067 = 31473104
43 + 31473061 = 31473104
67 + 31473037 = 31473104
73 + 31473031 = 31473104
277 + 31472827 = 31473104
331 + 31472773 = 31473104
811 + 31472293 = 31473104
937 + 31472167 = 31473104

Showing the first eight; more decompositions exist.
