Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498082, here are decompositions:

13 + 31498069 = 31498082
43 + 31498039 = 31498082
73 + 31498009 = 31498082
79 + 31498003 = 31498082
103 + 31497979 = 31498082
151 + 31497931 = 31498082
199 + 31497883 = 31498082
211 + 31497871 = 31498082

Showing the first eight; more decompositions exist.
