Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555852, here are decompositions:

11 + 31555841 = 31555852
71 + 31555781 = 31555852
89 + 31555763 = 31555852
113 + 31555739 = 31555852
191 + 31555661 = 31555852
281 + 31555571 = 31555852
311 + 31555541 = 31555852
359 + 31555493 = 31555852

Showing the first eight; more decompositions exist.
