Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463342, here are decompositions:

13 + 31463329 = 31463342
61 + 31463281 = 31463342
73 + 31463269 = 31463342
139 + 31463203 = 31463342
181 + 31463161 = 31463342
373 + 31462969 = 31463342
409 + 31462933 = 31463342
433 + 31462909 = 31463342

Showing the first eight; more decompositions exist.
