Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452650, here are decompositions:

43 + 31452607 = 31452650
67 + 31452583 = 31452650
79 + 31452571 = 31452650
157 + 31452493 = 31452650
199 + 31452451 = 31452650
283 + 31452367 = 31452650
349 + 31452301 = 31452650
367 + 31452283 = 31452650

Showing the first eight; more decompositions exist.
