Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131504, here are decompositions:

3 + 131501 = 131504
7 + 131497 = 131504
67 + 131437 = 131504
73 + 131431 = 131504
193 + 131311 = 131504
211 + 131293 = 131504
283 + 131221 = 131504
433 + 131071 = 131504

Showing the first eight; more decompositions exist.
