Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534898, here are decompositions:

19 + 31534879 = 31534898
67 + 31534831 = 31534898
79 + 31534819 = 31534898
97 + 31534801 = 31534898
229 + 31534669 = 31534898
337 + 31534561 = 31534898
397 + 31534501 = 31534898
457 + 31534441 = 31534898

Showing the first eight; more decompositions exist.
