Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051142, here are decompositions:

3 + 1051139 = 1051142
61 + 1051081 = 1051142
73 + 1051069 = 1051142
139 + 1051003 = 1051142
181 + 1050961 = 1051142
193 + 1050949 = 1051142
229 + 1050913 = 1051142
241 + 1050901 = 1051142

Showing the first eight; more decompositions exist.
