Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555410, here are decompositions:

23 + 31555387 = 31555410
79 + 31555331 = 31555410
83 + 31555327 = 31555410
97 + 31555313 = 31555410
113 + 31555297 = 31555410
151 + 31555259 = 31555410
157 + 31555253 = 31555410
167 + 31555243 = 31555410

Showing the first eight; more decompositions exist.
