Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021932, here are decompositions:

13 + 1021919 = 1021932
53 + 1021879 = 1021932
71 + 1021861 = 1021932
83 + 1021849 = 1021932
101 + 1021831 = 1021932
139 + 1021793 = 1021932
173 + 1021759 = 1021932
179 + 1021753 = 1021932

Showing the first eight; more decompositions exist.
