Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55642, here are decompositions:

3 + 55639 = 55642
11 + 55631 = 55642
23 + 55619 = 55642
53 + 55589 = 55642
101 + 55541 = 55642
113 + 55529 = 55642
131 + 55511 = 55642
173 + 55469 = 55642

Showing the first eight; more decompositions exist.
