Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462558, here are decompositions:

5 + 31462553 = 31462558
11 + 31462547 = 31462558
107 + 31462451 = 31462558
269 + 31462289 = 31462558
431 + 31462127 = 31462558
797 + 31461761 = 31462558
821 + 31461737 = 31462558
1217 + 31461341 = 31462558

Showing the first eight; more decompositions exist.
