Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473548, here are decompositions:

19 + 31473529 = 31473548
61 + 31473487 = 31473548
151 + 31473397 = 31473548
307 + 31473241 = 31473548
331 + 31473217 = 31473548
397 + 31473151 = 31473548
439 + 31473109 = 31473548
487 + 31473061 = 31473548

Showing the first eight; more decompositions exist.
