Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555714, here are decompositions:

17 + 31555697 = 31555714
53 + 31555661 = 31555714
83 + 31555631 = 31555714
107 + 31555607 = 31555714
173 + 31555541 = 31555714
383 + 31555331 = 31555714
401 + 31555313 = 31555714
461 + 31555253 = 31555714

Showing the first eight; more decompositions exist.
