Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185242, here are decompositions:

53 + 185189 = 185242
59 + 185183 = 185242
89 + 185153 = 185242
173 + 185069 = 185242
179 + 185063 = 185242
191 + 185051 = 185242
293 + 184949 = 185242
383 + 184859 = 185242

Showing the first eight; more decompositions exist.
