Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555594, here are decompositions:

23 + 31555571 = 31555594
53 + 31555541 = 31555594
101 + 31555493 = 31555594
263 + 31555331 = 31555594
281 + 31555313 = 31555594
383 + 31555211 = 31555594
461 + 31555133 = 31555594
563 + 31555031 = 31555594

Showing the first eight; more decompositions exist.
