Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972538, here are decompositions:

5 + 972533 = 972538
107 + 972431 = 972538
131 + 972407 = 972538
191 + 972347 = 972538
311 + 972227 = 972538
317 + 972221 = 972538
401 + 972137 = 972538
419 + 972119 = 972538

Showing the first eight; more decompositions exist.
