Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465050, here are decompositions:

11 + 31465039 = 31465050
17 + 31465033 = 31465050
47 + 31465003 = 31465050
59 + 31464991 = 31465050
83 + 31464967 = 31465050
103 + 31464947 = 31465050
109 + 31464941 = 31465050
167 + 31464883 = 31465050

Showing the first eight; more decompositions exist.
