Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489112, here are decompositions:

43 + 31489069 = 31489112
103 + 31489009 = 31489112
181 + 31488931 = 31489112
313 + 31488799 = 31489112
379 + 31488733 = 31489112
619 + 31488493 = 31489112
631 + 31488481 = 31489112
643 + 31488469 = 31489112

Showing the first eight; more decompositions exist.
