Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554074, here are decompositions:

31 + 31554043 = 31554074
61 + 31554013 = 31554074
241 + 31553833 = 31554074
271 + 31553803 = 31554074
313 + 31553761 = 31554074
367 + 31553707 = 31554074
457 + 31553617 = 31554074
547 + 31553527 = 31554074

Showing the first eight; more decompositions exist.
