Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537358, here are decompositions:

19 + 31537339 = 31537358
31 + 31537327 = 31537358
157 + 31537201 = 31537358
211 + 31537147 = 31537358
271 + 31537087 = 31537358
331 + 31537027 = 31537358
367 + 31536991 = 31537358
421 + 31536937 = 31537358

Showing the first eight; more decompositions exist.
