Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462630, here are decompositions:

41 + 31462589 = 31462630
47 + 31462583 = 31462630
53 + 31462577 = 31462630
83 + 31462547 = 31462630
149 + 31462481 = 31462630
179 + 31462451 = 31462630
191 + 31462439 = 31462630
197 + 31462433 = 31462630

Showing the first eight; more decompositions exist.
