Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463582, here are decompositions:

193 + 31463389 = 31463582
229 + 31463353 = 31463582
313 + 31463269 = 31463582
379 + 31463203 = 31463582
421 + 31463161 = 31463582
499 + 31463083 = 31463582
613 + 31462969 = 31463582
673 + 31462909 = 31463582

Showing the first eight; more decompositions exist.
