Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624854, here are decompositions:

5 + 31624849 = 31624854
17 + 31624837 = 31624854
47 + 31624807 = 31624854
71 + 31624783 = 31624854
73 + 31624781 = 31624854
101 + 31624753 = 31624854
113 + 31624741 = 31624854
137 + 31624717 = 31624854

Showing the first eight; more decompositions exist.
