Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627868, here are decompositions:

7 + 31627861 = 31627868
67 + 31627801 = 31627868
229 + 31627639 = 31627868
241 + 31627627 = 31627868
331 + 31627537 = 31627868
367 + 31627501 = 31627868
457 + 31627411 = 31627868
607 + 31627261 = 31627868

Showing the first eight; more decompositions exist.
