Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554374, here are decompositions:

13 + 31554361 = 31554374
37 + 31554337 = 31554374
193 + 31554181 = 31554374
211 + 31554163 = 31554374
331 + 31554043 = 31554374
541 + 31553833 = 31554374
571 + 31553803 = 31554374
613 + 31553761 = 31554374

Showing the first eight; more decompositions exist.
