Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055138, here are decompositions:

61 + 1055077 = 1055138
181 + 1054957 = 1055138
211 + 1054927 = 1055138
229 + 1054909 = 1055138
307 + 1054831 = 1055138
421 + 1054717 = 1055138
499 + 1054639 = 1055138
541 + 1054597 = 1055138

Showing the first eight; more decompositions exist.
