Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489196, here are decompositions:

3 + 31489193 = 31489196
19 + 31489177 = 31489196
127 + 31489069 = 31489196
337 + 31488859 = 31489196
397 + 31488799 = 31489196
463 + 31488733 = 31489196
577 + 31488619 = 31489196
727 + 31488469 = 31489196

Showing the first eight; more decompositions exist.
