Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051442, here are decompositions:

19 + 1051423 = 1051442
109 + 1051333 = 1051442
151 + 1051291 = 1051442
373 + 1051069 = 1051442
433 + 1051009 = 1051442
439 + 1051003 = 1051442
541 + 1050901 = 1051442
631 + 1050811 = 1051442

Showing the first eight; more decompositions exist.
