Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23042, here are decompositions:

3 + 23039 = 23042
13 + 23029 = 23042
31 + 23011 = 23042
79 + 22963 = 23042
181 + 22861 = 23042
373 + 22669 = 23042
421 + 22621 = 23042
499 + 22543 = 23042

Showing the first eight; more decompositions exist.
