Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61878, here are decompositions:

7 + 61871 = 61878
17 + 61861 = 61878
41 + 61837 = 61878
59 + 61819 = 61878
97 + 61781 = 61878
127 + 61751 = 61878
149 + 61729 = 61878
191 + 61687 = 61878

Showing the first eight; more decompositions exist.
