Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498968, here are decompositions:

5 + 31498963 = 31498968
19 + 31498949 = 31498968
37 + 31498931 = 31498968
71 + 31498897 = 31498968
89 + 31498879 = 31498968
101 + 31498867 = 31498968
131 + 31498837 = 31498968
139 + 31498829 = 31498968

Showing the first eight; more decompositions exist.
