Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055890, here are decompositions:

23 + 1055867 = 1055890
89 + 1055801 = 1055890
107 + 1055783 = 1055890
149 + 1055741 = 1055890
281 + 1055609 = 1055890
293 + 1055597 = 1055890
347 + 1055543 = 1055890
359 + 1055531 = 1055890

Showing the first eight; more decompositions exist.
