Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104042, here are decompositions:

61 + 103981 = 104042
73 + 103969 = 104042
79 + 103963 = 104042
139 + 103903 = 104042
199 + 103843 = 104042
229 + 103813 = 104042
241 + 103801 = 104042
373 + 103669 = 104042

Showing the first eight; more decompositions exist.
