Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452026, here are decompositions:

7 + 31452019 = 31452026
13 + 31452013 = 31452026
19 + 31452007 = 31452026
97 + 31451929 = 31452026
157 + 31451869 = 31452026
313 + 31451713 = 31452026
409 + 31451617 = 31452026
439 + 31451587 = 31452026

Showing the first eight; more decompositions exist.
