Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537450, here are decompositions:

17 + 31537433 = 31537450
41 + 31537409 = 31537450
59 + 31537391 = 31537450
137 + 31537313 = 31537450
179 + 31537271 = 31537450
227 + 31537223 = 31537450
317 + 31537133 = 31537450
353 + 31537097 = 31537450

Showing the first eight; more decompositions exist.
