Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548152, here are decompositions:

3 + 31548149 = 31548152
19 + 31548133 = 31548152
43 + 31548109 = 31548152
73 + 31548079 = 31548152
193 + 31547959 = 31548152
199 + 31547953 = 31548152
313 + 31547839 = 31548152
421 + 31547731 = 31548152

Showing the first eight; more decompositions exist.
