Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465554, here are decompositions:

7 + 31465547 = 31465554
73 + 31465481 = 31465554
103 + 31465451 = 31465554
137 + 31465417 = 31465554
163 + 31465391 = 31465554
191 + 31465363 = 31465554
233 + 31465321 = 31465554
311 + 31465243 = 31465554

Showing the first eight; more decompositions exist.
