Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972442, here are decompositions:

11 + 972431 = 972442
89 + 972353 = 972442
113 + 972329 = 972442
179 + 972263 = 972442
281 + 972161 = 972442
311 + 972131 = 972442
461 + 971981 = 972442
491 + 971951 = 972442

Showing the first eight; more decompositions exist.
