Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513302, here are decompositions:

43 + 31513259 = 31513302
83 + 31513219 = 31513302
89 + 31513213 = 31513302
101 + 31513201 = 31513302
109 + 31513193 = 31513302
179 + 31513123 = 31513302
211 + 31513091 = 31513302
229 + 31513073 = 31513302

Showing the first eight; more decompositions exist.
