Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488046, here are decompositions:

53 + 31487993 = 31488046
89 + 31487957 = 31488046
173 + 31487873 = 31488046
179 + 31487867 = 31488046
263 + 31487783 = 31488046
383 + 31487663 = 31488046
389 + 31487657 = 31488046
503 + 31487543 = 31488046

Showing the first eight; more decompositions exist.
