Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521108, here are decompositions:

61 + 521047 = 521108
67 + 521041 = 521108
127 + 520981 = 521108
139 + 520969 = 521108
151 + 520957 = 521108
241 + 520867 = 521108
271 + 520837 = 521108
349 + 520759 = 521108

Showing the first eight; more decompositions exist.
