Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972830, here are decompositions:

3 + 972827 = 972830
7 + 972823 = 972830
31 + 972799 = 972830
37 + 972793 = 972830
43 + 972787 = 972830
109 + 972721 = 972830
151 + 972679 = 972830
181 + 972649 = 972830

Showing the first eight; more decompositions exist.
