Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493034, here are decompositions:

5 + 31493029 = 31493034
17 + 31493017 = 31493034
37 + 31492997 = 31493034
43 + 31492991 = 31493034
71 + 31492963 = 31493034
101 + 31492933 = 31493034
113 + 31492921 = 31493034
127 + 31492907 = 31493034

Showing the first eight; more decompositions exist.
