Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537136, here are decompositions:

3 + 31537133 = 31537136
97 + 31537039 = 31537136
109 + 31537027 = 31537136
193 + 31536943 = 31537136
199 + 31536937 = 31537136
307 + 31536829 = 31537136
313 + 31536823 = 31537136
439 + 31536697 = 31537136

Showing the first eight; more decompositions exist.
