Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055720, here are decompositions:

7 + 1055713 = 1055720
31 + 1055689 = 1055720
109 + 1055611 = 1055720
283 + 1055437 = 1055720
307 + 1055413 = 1055720
313 + 1055407 = 1055720
349 + 1055371 = 1055720
373 + 1055347 = 1055720

Showing the first eight; more decompositions exist.
