Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461300, here are decompositions:

7 + 31461293 = 31461300
19 + 31461281 = 31461300
47 + 31461253 = 31461300
71 + 31461229 = 31461300
107 + 31461193 = 31461300
109 + 31461191 = 31461300
127 + 31461173 = 31461300
137 + 31461163 = 31461300

Showing the first eight; more decompositions exist.
