Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489954, here are decompositions:

5 + 31489949 = 31489954
11 + 31489943 = 31489954
53 + 31489901 = 31489954
71 + 31489883 = 31489954
113 + 31489841 = 31489954
137 + 31489817 = 31489954
233 + 31489721 = 31489954
281 + 31489673 = 31489954

Showing the first eight; more decompositions exist.
