Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460898, here are decompositions:

19 + 31460879 = 31460898
47 + 31460851 = 31460898
59 + 31460839 = 31460898
61 + 31460837 = 31460898
67 + 31460831 = 31460898
89 + 31460809 = 31460898
107 + 31460791 = 31460898
181 + 31460717 = 31460898

Showing the first eight; more decompositions exist.
