Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462588, here are decompositions:

5 + 31462583 = 31462588
11 + 31462577 = 31462588
41 + 31462547 = 31462588
107 + 31462481 = 31462588
137 + 31462451 = 31462588
149 + 31462439 = 31462588
239 + 31462349 = 31462588
461 + 31462127 = 31462588

Showing the first eight; more decompositions exist.
