Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538028, here are decompositions:

37 + 537991 = 538028
109 + 537919 = 538028
151 + 537877 = 538028
181 + 537847 = 538028
241 + 537787 = 538028
349 + 537679 = 538028
367 + 537661 = 538028
787 + 537241 = 538028

Showing the first eight; more decompositions exist.
