Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947542, here are decompositions:

3 + 947539 = 947542
41 + 947501 = 947542
59 + 947483 = 947542
131 + 947411 = 947542
173 + 947369 = 947542
191 + 947351 = 947542
359 + 947183 = 947542
509 + 947033 = 947542

Showing the first eight; more decompositions exist.
