Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560300, here are decompositions:

7 + 31560293 = 31560300
53 + 31560247 = 31560300
61 + 31560239 = 31560300
67 + 31560233 = 31560300
73 + 31560227 = 31560300
127 + 31560173 = 31560300
193 + 31560107 = 31560300
227 + 31560073 = 31560300

Showing the first eight; more decompositions exist.
