Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997442, here are decompositions:

3 + 997439 = 997442
73 + 997369 = 997442
109 + 997333 = 997442
163 + 997279 = 997442
223 + 997219 = 997442
241 + 997201 = 997442
331 + 997111 = 997442
373 + 997069 = 997442

Showing the first eight; more decompositions exist.
