Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4520, here are decompositions:

3 + 4517 = 4520
7 + 4513 = 4520
13 + 4507 = 4520
37 + 4483 = 4520
73 + 4447 = 4520
79 + 4441 = 4520
97 + 4423 = 4520
157 + 4363 = 4520

Showing the first eight; more decompositions exist.
