Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493052, here are decompositions:

5 + 31493047 = 31493052
13 + 31493039 = 31493052
23 + 31493029 = 31493052
43 + 31493009 = 31493052
61 + 31492991 = 31493052
89 + 31492963 = 31493052
109 + 31492943 = 31493052
131 + 31492921 = 31493052

Showing the first eight; more decompositions exist.
