Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493004, here are decompositions:

7 + 31492997 = 31493004
13 + 31492991 = 31493004
41 + 31492963 = 31493004
61 + 31492943 = 31493004
71 + 31492933 = 31493004
83 + 31492921 = 31493004
97 + 31492907 = 31493004
157 + 31492847 = 31493004

Showing the first eight; more decompositions exist.
