Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627898, here are decompositions:

19 + 31627879 = 31627898
37 + 31627861 = 31627898
97 + 31627801 = 31627898
271 + 31627627 = 31627898
331 + 31627567 = 31627898
397 + 31627501 = 31627898
487 + 31627411 = 31627898
541 + 31627357 = 31627898

Showing the first eight; more decompositions exist.
