Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553820, here are decompositions:

31 + 553789 = 553820
61 + 553759 = 553820
73 + 553747 = 553820
139 + 553681 = 553820
193 + 553627 = 553820
229 + 553591 = 553820
271 + 553549 = 553820
277 + 553543 = 553820

Showing the first eight; more decompositions exist.
