Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536764, here are decompositions:

31 + 31536733 = 31536764
67 + 31536697 = 31536764
151 + 31536613 = 31536764
157 + 31536607 = 31536764
283 + 31536481 = 31536764
367 + 31536397 = 31536764
373 + 31536391 = 31536764
541 + 31536223 = 31536764

Showing the first eight; more decompositions exist.
