Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627446, here are decompositions:

73 + 31627373 = 31627446
89 + 31627357 = 31627446
113 + 31627333 = 31627446
127 + 31627319 = 31627446
157 + 31627289 = 31627446
197 + 31627249 = 31627446
199 + 31627247 = 31627446
229 + 31627217 = 31627446

Showing the first eight; more decompositions exist.
