Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538554, here are decompositions:

31 + 538523 = 538554
41 + 538513 = 538554
43 + 538511 = 538554
67 + 538487 = 538554
73 + 538481 = 538554
83 + 538471 = 538554
97 + 538457 = 538554
131 + 538423 = 538554

Showing the first eight; more decompositions exist.
