Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452030, here are decompositions:

11 + 31452019 = 31452030
17 + 31452013 = 31452030
23 + 31452007 = 31452030
31 + 31451999 = 31452030
37 + 31451993 = 31452030
61 + 31451969 = 31452030
101 + 31451929 = 31452030
149 + 31451881 = 31452030

Showing the first eight; more decompositions exist.
