Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463436, here are decompositions:

7 + 31463429 = 31463436
29 + 31463407 = 31463436
47 + 31463389 = 31463436
73 + 31463363 = 31463436
83 + 31463353 = 31463436
107 + 31463329 = 31463436
167 + 31463269 = 31463436
223 + 31463213 = 31463436

Showing the first eight; more decompositions exist.
