Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503644, here are decompositions:

23 + 503621 = 503644
101 + 503543 = 503644
191 + 503453 = 503644
263 + 503381 = 503644
293 + 503351 = 503644
347 + 503297 = 503644
431 + 503213 = 503644
521 + 503123 = 503644

Showing the first eight; more decompositions exist.
