Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047442, here are decompositions:

23 + 1047419 = 1047442
101 + 1047341 = 1047442
131 + 1047311 = 1047442
269 + 1047173 = 1047442
311 + 1047131 = 1047442
353 + 1047089 = 1047442
401 + 1047041 = 1047442
443 + 1046999 = 1047442

Showing the first eight; more decompositions exist.
