Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997622, here are decompositions:

13 + 997609 = 997622
313 + 997309 = 997622
349 + 997273 = 997622
421 + 997201 = 997622
499 + 997123 = 997622
523 + 997099 = 997622
541 + 997081 = 997622
601 + 997021 = 997622

Showing the first eight; more decompositions exist.
