Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452534, here are decompositions:

5 + 31452529 = 31452534
7 + 31452527 = 31452534
13 + 31452521 = 31452534
17 + 31452517 = 31452534
37 + 31452497 = 31452534
41 + 31452493 = 31452534
53 + 31452481 = 31452534
73 + 31452461 = 31452534

Showing the first eight; more decompositions exist.
