Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61072, here are decompositions:

29 + 61043 = 61072
41 + 61031 = 61072
71 + 61001 = 61072
149 + 60923 = 61072
173 + 60899 = 61072
251 + 60821 = 61072
293 + 60779 = 61072
311 + 60761 = 61072

Showing the first eight; more decompositions exist.
