Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972142, here are decompositions:

5 + 972137 = 972142
11 + 972131 = 972142
23 + 972119 = 972142
29 + 972113 = 972142
71 + 972071 = 972142
113 + 972029 = 972142
191 + 971951 = 972142
239 + 971903 = 972142

Showing the first eight; more decompositions exist.
