Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550976, here are decompositions:

29 + 31550947 = 31550976
53 + 31550923 = 31550976
97 + 31550879 = 31550976
109 + 31550867 = 31550976
139 + 31550837 = 31550976
173 + 31550803 = 31550976
179 + 31550797 = 31550976
229 + 31550747 = 31550976

Showing the first eight; more decompositions exist.
