Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498136, here are decompositions:

13 + 31498123 = 31498136
67 + 31498069 = 31498136
97 + 31498039 = 31498136
127 + 31498009 = 31498136
139 + 31497997 = 31498136
157 + 31497979 = 31498136
277 + 31497859 = 31498136
379 + 31497757 = 31498136

Showing the first eight; more decompositions exist.
