Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81048, here are decompositions:

5 + 81043 = 81048
7 + 81041 = 81048
17 + 81031 = 81048
29 + 81019 = 81048
31 + 81017 = 81048
47 + 81001 = 81048
59 + 80989 = 81048
131 + 80917 = 81048

Showing the first eight; more decompositions exist.
