Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554026, here are decompositions:

13 + 31554013 = 31554026
43 + 31553983 = 31554026
193 + 31553833 = 31554026
223 + 31553803 = 31554026
307 + 31553719 = 31554026
367 + 31553659 = 31554026
409 + 31553617 = 31554026
499 + 31553527 = 31554026

Showing the first eight; more decompositions exist.
