Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627376, here are decompositions:

3 + 31627373 = 31627376
19 + 31627357 = 31627376
43 + 31627333 = 31627376
73 + 31627303 = 31627376
127 + 31627249 = 31627376
139 + 31627237 = 31627376
307 + 31627069 = 31627376
349 + 31627027 = 31627376

Showing the first eight; more decompositions exist.
