Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51090, here are decompositions:

19 + 51071 = 51090
29 + 51061 = 51090
31 + 51059 = 51090
43 + 51047 = 51090
47 + 51043 = 51090
59 + 51031 = 51090
89 + 51001 = 51090
97 + 50993 = 51090

Showing the first eight; more decompositions exist.
