Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498956, here are decompositions:

7 + 31498949 = 31498956
43 + 31498913 = 31498956
59 + 31498897 = 31498956
89 + 31498867 = 31498956
103 + 31498853 = 31498956
107 + 31498849 = 31498956
109 + 31498847 = 31498956
127 + 31498829 = 31498956

Showing the first eight; more decompositions exist.
