Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997868, here are decompositions:

61 + 997807 = 997868
127 + 997741 = 997868
241 + 997627 = 997868
271 + 997597 = 997868
499 + 997369 = 997868
541 + 997327 = 997868
601 + 997267 = 997868
661 + 997207 = 997868

Showing the first eight; more decompositions exist.
