Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187042, here are decompositions:

83 + 186959 = 187042
173 + 186869 = 187042
269 + 186773 = 187042
281 + 186761 = 187042
353 + 186689 = 187042
389 + 186653 = 187042
461 + 186581 = 187042
491 + 186551 = 187042

Showing the first eight; more decompositions exist.
