Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532388, here are decompositions:

61 + 532327 = 532388
127 + 532261 = 532388
139 + 532249 = 532388
229 + 532159 = 532388
379 + 532009 = 532388
487 + 531901 = 532388
541 + 531847 = 532388
547 + 531841 = 532388

Showing the first eight; more decompositions exist.
