Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555526, here are decompositions:

97 + 31555429 = 31555526
139 + 31555387 = 31555526
199 + 31555327 = 31555526
229 + 31555297 = 31555526
283 + 31555243 = 31555526
433 + 31555093 = 31555526
463 + 31555063 = 31555526
577 + 31554949 = 31555526

Showing the first eight; more decompositions exist.
