Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468688, here are decompositions:

241 + 31468447 = 31468688
457 + 31468231 = 31468688
487 + 31468201 = 31468688
541 + 31468147 = 31468688
661 + 31468027 = 31468688
739 + 31467949 = 31468688
751 + 31467937 = 31468688
859 + 31467829 = 31468688

Showing the first eight; more decompositions exist.
