Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576074, here are decompositions:

7 + 31576067 = 31576074
37 + 31576037 = 31576074
43 + 31576031 = 31576074
67 + 31576007 = 31576074
71 + 31576003 = 31576074
73 + 31576001 = 31576074
83 + 31575991 = 31576074
137 + 31575937 = 31576074

Showing the first eight; more decompositions exist.
