Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555092, here are decompositions:

11 + 31555081 = 31555092
13 + 31555079 = 31555092
29 + 31555063 = 31555092
31 + 31555061 = 31555092
61 + 31555031 = 31555092
71 + 31555021 = 31555092
73 + 31555019 = 31555092
131 + 31554961 = 31555092

Showing the first eight; more decompositions exist.
