Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997402, here are decompositions:

11 + 997391 = 997402
23 + 997379 = 997402
59 + 997343 = 997402
83 + 997319 = 997402
239 + 997163 = 997402
251 + 997151 = 997402
281 + 997121 = 997402
293 + 997109 = 997402

Showing the first eight; more decompositions exist.
