Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452074, here are decompositions:

13 + 31452061 = 31452074
61 + 31452013 = 31452074
67 + 31452007 = 31452074
193 + 31451881 = 31452074
457 + 31451617 = 31452074
487 + 31451587 = 31452074
547 + 31451527 = 31452074
571 + 31451503 = 31452074

Showing the first eight; more decompositions exist.
