Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538382, here are decompositions:

73 + 538309 = 538382
79 + 538303 = 538382
181 + 538201 = 538382
223 + 538159 = 538382
331 + 538051 = 538382
463 + 537919 = 538382
499 + 537883 = 538382
541 + 537841 = 538382

Showing the first eight; more decompositions exist.
