Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57642, here are decompositions:

5 + 57637 = 57642
41 + 57601 = 57642
71 + 57571 = 57642
83 + 57559 = 57642
113 + 57529 = 57642
139 + 57503 = 57642
149 + 57493 = 57642
229 + 57413 = 57642

Showing the first eight; more decompositions exist.
