Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452536, here are decompositions:

7 + 31452529 = 31452536
19 + 31452517 = 31452536
43 + 31452493 = 31452536
337 + 31452199 = 31452536
439 + 31452097 = 31452536
457 + 31452079 = 31452536
523 + 31452013 = 31452536
607 + 31451929 = 31452536

Showing the first eight; more decompositions exist.
