Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473996, here are decompositions:

5 + 31473991 = 31473996
19 + 31473977 = 31473996
79 + 31473917 = 31473996
89 + 31473907 = 31473996
109 + 31473887 = 31473996
149 + 31473847 = 31473996
157 + 31473839 = 31473996
263 + 31473733 = 31473996

Showing the first eight; more decompositions exist.
