Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463648, here are decompositions:

61 + 31463587 = 31463648
241 + 31463407 = 31463648
331 + 31463317 = 31463648
367 + 31463281 = 31463648
379 + 31463269 = 31463648
421 + 31463227 = 31463648
487 + 31463161 = 31463648
571 + 31463077 = 31463648

Showing the first eight; more decompositions exist.
