Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971824, here are decompositions:

3 + 971821 = 971824
41 + 971783 = 971824
71 + 971753 = 971824
101 + 971723 = 971824
131 + 971693 = 971824
173 + 971651 = 971824
233 + 971591 = 971824
263 + 971561 = 971824

Showing the first eight; more decompositions exist.
