Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473300, here are decompositions:

17 + 31473283 = 31473300
37 + 31473263 = 31473300
59 + 31473241 = 31473300
83 + 31473217 = 31473300
97 + 31473203 = 31473300
109 + 31473191 = 31473300
113 + 31473187 = 31473300
127 + 31473173 = 31473300

Showing the first eight; more decompositions exist.
