Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455414, here are decompositions:

5 + 31455409 = 31455414
17 + 31455397 = 31455414
43 + 31455371 = 31455414
47 + 31455367 = 31455414
101 + 31455313 = 31455414
113 + 31455301 = 31455414
191 + 31455223 = 31455414
283 + 31455131 = 31455414

Showing the first eight; more decompositions exist.
