Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546434, here are decompositions:

13 + 31546421 = 31546434
41 + 31546393 = 31546434
47 + 31546387 = 31546434
83 + 31546351 = 31546434
97 + 31546337 = 31546434
131 + 31546303 = 31546434
151 + 31546283 = 31546434
167 + 31546267 = 31546434

Showing the first eight; more decompositions exist.
