Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554626, here are decompositions:

7 + 31554619 = 31554626
13 + 31554613 = 31554626
43 + 31554583 = 31554626
109 + 31554517 = 31554626
163 + 31554463 = 31554626
193 + 31554433 = 31554626
463 + 31554163 = 31554626
613 + 31554013 = 31554626

Showing the first eight; more decompositions exist.
