Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558890, here are decompositions:

61 + 558829 = 558890
97 + 558793 = 558890
103 + 558787 = 558890
109 + 558781 = 558890
229 + 558661 = 558890
307 + 558583 = 558890
349 + 558541 = 558890
421 + 558469 = 558890

Showing the first eight; more decompositions exist.
