Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548452, here are decompositions:

109 + 31548343 = 31548452
139 + 31548313 = 31548452
151 + 31548301 = 31548452
349 + 31548103 = 31548452
373 + 31548079 = 31548452
421 + 31548031 = 31548452
499 + 31547953 = 31548452
601 + 31547851 = 31548452

Showing the first eight; more decompositions exist.
