Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574766, here are decompositions:

19 + 31574747 = 31574766
43 + 31574723 = 31574766
73 + 31574693 = 31574766
79 + 31574687 = 31574766
89 + 31574677 = 31574766
109 + 31574657 = 31574766
127 + 31574639 = 31574766
269 + 31574497 = 31574766

Showing the first eight; more decompositions exist.
