Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997574, here are decompositions:

241 + 997333 = 997574
307 + 997267 = 997574
367 + 997207 = 997574
373 + 997201 = 997574
421 + 997153 = 997574
433 + 997141 = 997574
463 + 997111 = 997574
601 + 996973 = 997574

Showing the first eight; more decompositions exist.
