Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12042, here are decompositions:

5 + 12037 = 12042
31 + 12011 = 12042
61 + 11981 = 12042
71 + 11971 = 12042
73 + 11969 = 12042
83 + 11959 = 12042
89 + 11953 = 12042
101 + 11941 = 12042

Showing the first eight; more decompositions exist.
