Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546488, here are decompositions:

5 + 31546483 = 31546488
19 + 31546469 = 31546488
31 + 31546457 = 31546488
37 + 31546451 = 31546488
67 + 31546421 = 31546488
101 + 31546387 = 31546488
137 + 31546351 = 31546488
139 + 31546349 = 31546488

Showing the first eight; more decompositions exist.
