Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055772, here are decompositions:

31 + 1055741 = 1055772
41 + 1055731 = 1055772
59 + 1055713 = 1055772
83 + 1055689 = 1055772
101 + 1055671 = 1055772
163 + 1055609 = 1055772
181 + 1055591 = 1055772
229 + 1055543 = 1055772

Showing the first eight; more decompositions exist.
