Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493044, here are decompositions:

5 + 31493039 = 31493044
47 + 31492997 = 31493044
53 + 31492991 = 31493044
101 + 31492943 = 31493044
137 + 31492907 = 31493044
197 + 31492847 = 31493044
263 + 31492781 = 31493044
293 + 31492751 = 31493044

Showing the first eight; more decompositions exist.
