Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627378, here are decompositions:

5 + 31627373 = 31627378
59 + 31627319 = 31627378
89 + 31627289 = 31627378
131 + 31627247 = 31627378
227 + 31627151 = 31627378
257 + 31627121 = 31627378
401 + 31626977 = 31627378
479 + 31626899 = 31627378

Showing the first eight; more decompositions exist.
