Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972742, here are decompositions:

41 + 972701 = 972742
59 + 972683 = 972742
131 + 972611 = 972742
269 + 972473 = 972742
311 + 972431 = 972742
389 + 972353 = 972742
479 + 972263 = 972742
521 + 972221 = 972742

Showing the first eight; more decompositions exist.
