Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550578, here are decompositions:

37 + 550541 = 550578
47 + 550531 = 550578
59 + 550519 = 550578
89 + 550489 = 550578
107 + 550471 = 550578
109 + 550469 = 550578
131 + 550447 = 550578
137 + 550441 = 550578

Showing the first eight; more decompositions exist.
