Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554506, here are decompositions:

13 + 31554493 = 31554506
43 + 31554463 = 31554506
73 + 31554433 = 31554506
97 + 31554409 = 31554506
223 + 31554283 = 31554506
307 + 31554199 = 31554506
433 + 31554073 = 31554506
463 + 31554043 = 31554506

Showing the first eight; more decompositions exist.
