Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548032, here are decompositions:

3 + 31548029 = 31548032
73 + 31547959 = 31548032
79 + 31547953 = 31548032
181 + 31547851 = 31548032
193 + 31547839 = 31548032
199 + 31547833 = 31548032
283 + 31547749 = 31548032
331 + 31547701 = 31548032

Showing the first eight; more decompositions exist.
