Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452654, here are decompositions:

5 + 31452649 = 31452654
31 + 31452623 = 31452654
47 + 31452607 = 31452654
67 + 31452587 = 31452654
71 + 31452583 = 31452654
83 + 31452571 = 31452654
127 + 31452527 = 31452654
137 + 31452517 = 31452654

Showing the first eight; more decompositions exist.
