Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548746, here are decompositions:

3 + 31548743 = 31548746
7 + 31548739 = 31548746
13 + 31548733 = 31548746
127 + 31548619 = 31548746
199 + 31548547 = 31548746
433 + 31548313 = 31548746
613 + 31548133 = 31548746
643 + 31548103 = 31548746

Showing the first eight; more decompositions exist.
