Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103042, here are decompositions:

41 + 103001 = 103042
59 + 102983 = 103042
89 + 102953 = 103042
113 + 102929 = 103042
131 + 102911 = 103042
281 + 102761 = 103042
389 + 102653 = 103042
431 + 102611 = 103042

Showing the first eight; more decompositions exist.
