Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489274, here are decompositions:

31 + 31489243 = 31489274
97 + 31489177 = 31489274
127 + 31489147 = 31489274
211 + 31489063 = 31489274
283 + 31488991 = 31489274
367 + 31488907 = 31489274
541 + 31488733 = 31489274
643 + 31488631 = 31489274

Showing the first eight; more decompositions exist.
