Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627362, here are decompositions:

5 + 31627357 = 31627362
29 + 31627333 = 31627362
43 + 31627319 = 31627362
59 + 31627303 = 31627362
73 + 31627289 = 31627362
101 + 31627261 = 31627362
113 + 31627249 = 31627362
211 + 31627151 = 31627362

Showing the first eight; more decompositions exist.
