Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498062, here are decompositions:

19 + 31498043 = 31498062
23 + 31498039 = 31498062
53 + 31498009 = 31498062
59 + 31498003 = 31498062
83 + 31497979 = 31498062
131 + 31497931 = 31498062
179 + 31497883 = 31498062
191 + 31497871 = 31498062

Showing the first eight; more decompositions exist.
