Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452060, here are decompositions:

19 + 31452041 = 31452060
41 + 31452019 = 31452060
47 + 31452013 = 31452060
53 + 31452007 = 31452060
61 + 31451999 = 31452060
67 + 31451993 = 31452060
131 + 31451929 = 31452060
151 + 31451909 = 31452060

Showing the first eight; more decompositions exist.
