Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537396, here are decompositions:

5 + 31537391 = 31537396
83 + 31537313 = 31537396
89 + 31537307 = 31537396
167 + 31537229 = 31537396
173 + 31537223 = 31537396
263 + 31537133 = 31537396
269 + 31537127 = 31537396
347 + 31537049 = 31537396

Showing the first eight; more decompositions exist.
