Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627468, here are decompositions:

149 + 31627319 = 31627468
179 + 31627289 = 31627468
251 + 31627217 = 31627468
317 + 31627151 = 31627468
347 + 31627121 = 31627468
461 + 31627007 = 31627468
491 + 31626977 = 31627468
569 + 31626899 = 31627468

Showing the first eight; more decompositions exist.
