Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548674, here are decompositions:

61 + 31548613 = 31548674
97 + 31548577 = 31548674
127 + 31548547 = 31548674
331 + 31548343 = 31548674
373 + 31548301 = 31548674
541 + 31548133 = 31548674
571 + 31548103 = 31548674
643 + 31548031 = 31548674

Showing the first eight; more decompositions exist.
