Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548362, here are decompositions:

19 + 31548343 = 31548362
31 + 31548331 = 31548362
61 + 31548301 = 31548362
229 + 31548133 = 31548362
283 + 31548079 = 31548362
331 + 31548031 = 31548362
409 + 31547953 = 31548362
523 + 31547839 = 31548362

Showing the first eight; more decompositions exist.
