Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554534, here are decompositions:

7 + 31554527 = 31554534
17 + 31554517 = 31554534
23 + 31554511 = 31554534
41 + 31554493 = 31554534
61 + 31554473 = 31554534
71 + 31554463 = 31554534
101 + 31554433 = 31554534
173 + 31554361 = 31554534

Showing the first eight; more decompositions exist.
