Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473188, here are decompositions:

37 + 31473151 = 31473188
79 + 31473109 = 31473188
127 + 31473061 = 31473188
151 + 31473037 = 31473188
157 + 31473031 = 31473188
337 + 31472851 = 31473188
349 + 31472839 = 31473188
577 + 31472611 = 31473188

Showing the first eight; more decompositions exist.
