Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64520, here are decompositions:

7 + 64513 = 64520
31 + 64489 = 64520
37 + 64483 = 64520
67 + 64453 = 64520
139 + 64381 = 64520
193 + 64327 = 64520
241 + 64279 = 64520
283 + 64237 = 64520

Showing the first eight; more decompositions exist.
