Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626302, here are decompositions:

73 + 31626229 = 31626302
109 + 31626193 = 31626302
193 + 31626109 = 31626302
223 + 31626079 = 31626302
229 + 31626073 = 31626302
283 + 31626019 = 31626302
349 + 31625953 = 31626302
523 + 31625779 = 31626302

Showing the first eight; more decompositions exist.
