Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47090, here are decompositions:

3 + 47087 = 47090
31 + 47059 = 47090
73 + 47017 = 47090
97 + 46993 = 47090
157 + 46933 = 47090
223 + 46867 = 47090
229 + 46861 = 47090
271 + 46819 = 47090

Showing the first eight; more decompositions exist.
