Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534530, here are decompositions:

29 + 31534501 = 31534530
37 + 31534493 = 31534530
43 + 31534487 = 31534530
47 + 31534483 = 31534530
73 + 31534457 = 31534530
89 + 31534441 = 31534530
101 + 31534429 = 31534530
103 + 31534427 = 31534530

Showing the first eight; more decompositions exist.
