Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007442, here are decompositions:

13 + 1007429 = 1007442
41 + 1007401 = 1007442
61 + 1007381 = 1007442
83 + 1007359 = 1007442
89 + 1007353 = 1007442
103 + 1007339 = 1007442
193 + 1007249 = 1007442
199 + 1007243 = 1007442

Showing the first eight; more decompositions exist.
