Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489076, here are decompositions:

7 + 31489069 = 31489076
13 + 31489063 = 31489076
67 + 31489009 = 31489076
97 + 31488979 = 31489076
277 + 31488799 = 31489076
457 + 31488619 = 31489076
607 + 31488469 = 31489076
613 + 31488463 = 31489076

Showing the first eight; more decompositions exist.
