Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15090, here are decompositions:

7 + 15083 = 15090
13 + 15077 = 15090
17 + 15073 = 15090
29 + 15061 = 15090
37 + 15053 = 15090
59 + 15031 = 15090
73 + 15017 = 15090
107 + 14983 = 15090

Showing the first eight; more decompositions exist.
