Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47642, here are decompositions:

3 + 47639 = 47642
13 + 47629 = 47642
19 + 47623 = 47642
43 + 47599 = 47642
61 + 47581 = 47642
73 + 47569 = 47642
79 + 47563 = 47642
109 + 47533 = 47642

Showing the first eight; more decompositions exist.
