Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554588, here are decompositions:

5 + 31554583 = 31554588
17 + 31554571 = 31554588
19 + 31554569 = 31554588
47 + 31554541 = 31554588
61 + 31554527 = 31554588
71 + 31554517 = 31554588
139 + 31554449 = 31554588
179 + 31554409 = 31554588

Showing the first eight; more decompositions exist.
