Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455534, here are decompositions:

13 + 31455521 = 31455534
31 + 31455503 = 31455534
101 + 31455433 = 31455534
107 + 31455427 = 31455534
137 + 31455397 = 31455534
163 + 31455371 = 31455534
167 + 31455367 = 31455534
233 + 31455301 = 31455534

Showing the first eight; more decompositions exist.
