Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452048, here are decompositions:

7 + 31452041 = 31452048
29 + 31452019 = 31452048
41 + 31452007 = 31452048
79 + 31451969 = 31452048
139 + 31451909 = 31452048
167 + 31451881 = 31452048
179 + 31451869 = 31452048
191 + 31451857 = 31452048

Showing the first eight; more decompositions exist.
