Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555596, here are decompositions:

47 + 31555549 = 31555596
53 + 31555543 = 31555596
103 + 31555493 = 31555596
157 + 31555439 = 31555596
167 + 31555429 = 31555596
269 + 31555327 = 31555596
277 + 31555319 = 31555596
283 + 31555313 = 31555596

Showing the first eight; more decompositions exist.
