Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538100, here are decompositions:

7 + 538093 = 538100
109 + 537991 = 538100
181 + 537919 = 538100
223 + 537877 = 538100
307 + 537793 = 538100
313 + 537787 = 538100
331 + 537769 = 538100
397 + 537703 = 538100

Showing the first eight; more decompositions exist.
