Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555614, here are decompositions:

7 + 31555607 = 31555614
11 + 31555603 = 31555614
43 + 31555571 = 31555614
71 + 31555543 = 31555614
73 + 31555541 = 31555614
227 + 31555387 = 31555614
283 + 31555331 = 31555614
317 + 31555297 = 31555614

Showing the first eight; more decompositions exist.
