Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619958, here are decompositions:

5 + 31619953 = 31619958
47 + 31619911 = 31619958
89 + 31619869 = 31619958
109 + 31619849 = 31619958
137 + 31619821 = 31619958
151 + 31619807 = 31619958
157 + 31619801 = 31619958
197 + 31619761 = 31619958

Showing the first eight; more decompositions exist.
