Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552820, here are decompositions:

11 + 552809 = 552820
29 + 552791 = 552820
71 + 552749 = 552820
89 + 552731 = 552820
113 + 552707 = 552820
239 + 552581 = 552820
293 + 552527 = 552820
347 + 552473 = 552820

Showing the first eight; more decompositions exist.
