Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574776, here are decompositions:

3 + 31574773 = 31574776
29 + 31574747 = 31574776
53 + 31574723 = 31574776
83 + 31574693 = 31574776
89 + 31574687 = 31574776
137 + 31574639 = 31574776
269 + 31574507 = 31574776
347 + 31574429 = 31574776

Showing the first eight; more decompositions exist.
