Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462554, here are decompositions:

7 + 31462547 = 31462554
23 + 31462531 = 31462554
47 + 31462507 = 31462554
73 + 31462481 = 31462554
83 + 31462471 = 31462554
103 + 31462451 = 31462554
113 + 31462441 = 31462554
173 + 31462381 = 31462554

Showing the first eight; more decompositions exist.
