Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051988, here are decompositions:

31 + 1051957 = 1051988
61 + 1051927 = 1051988
109 + 1051879 = 1051988
139 + 1051849 = 1051988
199 + 1051789 = 1051988
229 + 1051759 = 1051988
241 + 1051747 = 1051988
271 + 1051717 = 1051988

Showing the first eight; more decompositions exist.
