Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003438, here are decompositions:

5 + 1003433 = 1003438
41 + 1003397 = 1003438
71 + 1003367 = 1003438
89 + 1003349 = 1003438
101 + 1003337 = 1003438
131 + 1003307 = 1003438
179 + 1003259 = 1003438
197 + 1003241 = 1003438

Showing the first eight; more decompositions exist.
