Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61872, here are decompositions:

11 + 61861 = 61872
29 + 61843 = 61872
53 + 61819 = 61872
59 + 61813 = 61872
149 + 61723 = 61872
191 + 61681 = 61872
199 + 61673 = 61872
229 + 61643 = 61872

Showing the first eight; more decompositions exist.
