Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27090, here are decompositions:

13 + 27077 = 27090
17 + 27073 = 27090
23 + 27067 = 27090
29 + 27061 = 27090
31 + 27059 = 27090
47 + 27043 = 27090
59 + 27031 = 27090
73 + 27017 = 27090

Showing the first eight; more decompositions exist.
