Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628098, here are decompositions:

137 + 31627961 = 31628098
149 + 31627949 = 31628098
167 + 31627931 = 31628098
347 + 31627751 = 31628098
449 + 31627649 = 31628098
521 + 31627577 = 31628098
587 + 31627511 = 31628098
809 + 31627289 = 31628098

Showing the first eight; more decompositions exist.
