Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993972, here are decompositions:

11 + 993961 = 993972
29 + 993943 = 993972
53 + 993919 = 993972
59 + 993913 = 993972
79 + 993893 = 993972
103 + 993869 = 993972
131 + 993841 = 993972
149 + 993823 = 993972

Showing the first eight; more decompositions exist.
