Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493060, here are decompositions:

3 + 31493057 = 31493060
7 + 31493053 = 31493060
13 + 31493047 = 31493060
31 + 31493029 = 31493060
43 + 31493017 = 31493060
97 + 31492963 = 31493060
127 + 31492933 = 31493060
139 + 31492921 = 31493060

Showing the first eight; more decompositions exist.
