Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972520, here are decompositions:

47 + 972473 = 972520
89 + 972431 = 972520
113 + 972407 = 972520
167 + 972353 = 972520
173 + 972347 = 972520
191 + 972329 = 972520
257 + 972263 = 972520
293 + 972227 = 972520

Showing the first eight; more decompositions exist.
