Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489914, here are decompositions:

13 + 31489901 = 31489914
31 + 31489883 = 31489914
41 + 31489873 = 31489914
73 + 31489841 = 31489914
97 + 31489817 = 31489914
163 + 31489751 = 31489914
167 + 31489747 = 31489914
191 + 31489723 = 31489914

Showing the first eight; more decompositions exist.
