Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548634, here are decompositions:

41 + 31548593 = 31548634
71 + 31548563 = 31548634
83 + 31548551 = 31548634
101 + 31548533 = 31548634
107 + 31548527 = 31548634
113 + 31548521 = 31548634
167 + 31548467 = 31548634
191 + 31548443 = 31548634

Showing the first eight; more decompositions exist.
