Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588098, here are decompositions:

11 + 31588087 = 31588098
37 + 31588061 = 31588098
79 + 31588019 = 31588098
137 + 31587961 = 31588098
149 + 31587949 = 31588098
239 + 31587859 = 31588098
281 + 31587817 = 31588098
317 + 31587781 = 31588098

Showing the first eight; more decompositions exist.
