Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627348, here are decompositions:

29 + 31627319 = 31627348
59 + 31627289 = 31627348
101 + 31627247 = 31627348
131 + 31627217 = 31627348
197 + 31627151 = 31627348
227 + 31627121 = 31627348
257 + 31627091 = 31627348
449 + 31626899 = 31627348

Showing the first eight; more decompositions exist.
