Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473464, here are decompositions:

7 + 31473457 = 31473464
67 + 31473397 = 31473464
151 + 31473313 = 31473464
181 + 31473283 = 31473464
223 + 31473241 = 31473464
277 + 31473187 = 31473464
313 + 31473151 = 31473464
397 + 31473067 = 31473464

Showing the first eight; more decompositions exist.
