Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498080, here are decompositions:

11 + 31498069 = 31498080
37 + 31498043 = 31498080
41 + 31498039 = 31498080
71 + 31498009 = 31498080
73 + 31498007 = 31498080
83 + 31497997 = 31498080
101 + 31497979 = 31498080
139 + 31497941 = 31498080

Showing the first eight; more decompositions exist.
