Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537236, here are decompositions:

7 + 31537229 = 31537236
13 + 31537223 = 31537236
83 + 31537153 = 31537236
89 + 31537147 = 31537236
103 + 31537133 = 31537236
109 + 31537127 = 31537236
139 + 31537097 = 31537236
149 + 31537087 = 31537236

Showing the first eight; more decompositions exist.
