Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554594, here are decompositions:

11 + 31554583 = 31554594
23 + 31554571 = 31554594
53 + 31554541 = 31554594
67 + 31554527 = 31554594
83 + 31554511 = 31554594
101 + 31554493 = 31554594
131 + 31554463 = 31554594
193 + 31554401 = 31554594

Showing the first eight; more decompositions exist.
