Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576050, here are decompositions:

13 + 31576037 = 31576050
19 + 31576031 = 31576050
41 + 31576009 = 31576050
43 + 31576007 = 31576050
47 + 31576003 = 31576050
59 + 31575991 = 31576050
113 + 31575937 = 31576050
127 + 31575923 = 31576050

Showing the first eight; more decompositions exist.
