Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546970, here are decompositions:

61 + 31546909 = 31546970
79 + 31546891 = 31546970
109 + 31546861 = 31546970
127 + 31546843 = 31546970
139 + 31546831 = 31546970
157 + 31546813 = 31546970
163 + 31546807 = 31546970
181 + 31546789 = 31546970

Showing the first eight; more decompositions exist.
