Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463300, here are decompositions:

19 + 31463281 = 31463300
31 + 31463269 = 31463300
73 + 31463227 = 31463300
97 + 31463203 = 31463300
103 + 31463197 = 31463300
139 + 31463161 = 31463300
163 + 31463137 = 31463300
223 + 31463077 = 31463300

Showing the first eight; more decompositions exist.
