Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553978, here are decompositions:

17 + 553961 = 553978
59 + 553919 = 553978
167 + 553811 = 553978
251 + 553727 = 553978
311 + 553667 = 553978
389 + 553589 = 553978
449 + 553529 = 553978
461 + 553517 = 553978

Showing the first eight; more decompositions exist.
