Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537366, here are decompositions:

53 + 31537313 = 31537366
59 + 31537307 = 31537366
137 + 31537229 = 31537366
233 + 31537133 = 31537366
239 + 31537127 = 31537366
269 + 31537097 = 31537366
317 + 31537049 = 31537366
383 + 31536983 = 31537366

Showing the first eight; more decompositions exist.
