Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452764, here are decompositions:

37 + 31452727 = 31452764
43 + 31452721 = 31452764
97 + 31452667 = 31452764
157 + 31452607 = 31452764
181 + 31452583 = 31452764
193 + 31452571 = 31452764
271 + 31452493 = 31452764
283 + 31452481 = 31452764

Showing the first eight; more decompositions exist.
