Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471642, here are decompositions:

23 + 471619 = 471642
53 + 471589 = 471642
71 + 471571 = 471642
89 + 471553 = 471642
103 + 471539 = 471642
109 + 471533 = 471642
139 + 471503 = 471642
191 + 471451 = 471642

Showing the first eight; more decompositions exist.
