Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452506, here are decompositions:

13 + 31452493 = 31452506
139 + 31452367 = 31452506
223 + 31452283 = 31452506
307 + 31452199 = 31452506
409 + 31452097 = 31452506
487 + 31452019 = 31452506
499 + 31452007 = 31452506
577 + 31451929 = 31452506

Showing the first eight; more decompositions exist.
