Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473102, here are decompositions:

19 + 31473083 = 31473102
41 + 31473061 = 31473102
61 + 31473041 = 31473102
71 + 31473031 = 31473102
139 + 31472963 = 31473102
173 + 31472929 = 31473102
211 + 31472891 = 31473102
223 + 31472879 = 31473102

Showing the first eight; more decompositions exist.
