Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7442, here are decompositions:

31 + 7411 = 7442
73 + 7369 = 7442
109 + 7333 = 7442
199 + 7243 = 7442
223 + 7219 = 7442
229 + 7213 = 7442
283 + 7159 = 7442
313 + 7129 = 7442

Showing the first eight; more decompositions exist.
