Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600898, here are decompositions:

37 + 31600861 = 31600898
97 + 31600801 = 31600898
127 + 31600771 = 31600898
157 + 31600741 = 31600898
181 + 31600717 = 31600898
229 + 31600669 = 31600898
349 + 31600549 = 31600898
367 + 31600531 = 31600898

Showing the first eight; more decompositions exist.
