Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473154, here are decompositions:

3 + 31473151 = 31473154
47 + 31473107 = 31473154
71 + 31473083 = 31473154
113 + 31473041 = 31473154
191 + 31472963 = 31473154
227 + 31472927 = 31473154
263 + 31472891 = 31473154
347 + 31472807 = 31473154

Showing the first eight; more decompositions exist.
