Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76520, here are decompositions:

13 + 76507 = 76520
79 + 76441 = 76520
97 + 76423 = 76520
151 + 76369 = 76520
271 + 76249 = 76520
277 + 76243 = 76520
307 + 76213 = 76520
313 + 76207 = 76520

Showing the first eight; more decompositions exist.
