Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462584, here are decompositions:

5 + 31462579 = 31462584
7 + 31462577 = 31462584
11 + 31462573 = 31462584
31 + 31462553 = 31462584
37 + 31462547 = 31462584
53 + 31462531 = 31462584
103 + 31462481 = 31462584
113 + 31462471 = 31462584

Showing the first eight; more decompositions exist.
