Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548422, here are decompositions:

79 + 31548343 = 31548422
109 + 31548313 = 31548422
313 + 31548109 = 31548422
463 + 31547959 = 31548422
571 + 31547851 = 31548422
673 + 31547749 = 31548422
691 + 31547731 = 31548422
739 + 31547683 = 31548422

Showing the first eight; more decompositions exist.
