Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446300, here are decompositions:

43 + 31446257 = 31446300
47 + 31446253 = 31446300
59 + 31446241 = 31446300
71 + 31446229 = 31446300
73 + 31446227 = 31446300
89 + 31446211 = 31446300
167 + 31446133 = 31446300
199 + 31446101 = 31446300

Showing the first eight; more decompositions exist.
