Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527744, here are decompositions:

41 + 31527703 = 31527744
43 + 31527701 = 31527744
47 + 31527697 = 31527744
67 + 31527677 = 31527744
167 + 31527577 = 31527744
211 + 31527533 = 31527744
223 + 31527521 = 31527744
263 + 31527481 = 31527744

Showing the first eight; more decompositions exist.
