Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537098, here are decompositions:

11 + 31537087 = 31537098
59 + 31537039 = 31537098
71 + 31537027 = 31537098
97 + 31537001 = 31537098
107 + 31536991 = 31537098
139 + 31536959 = 31537098
181 + 31536917 = 31537098
227 + 31536871 = 31537098

Showing the first eight; more decompositions exist.
