Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188242, here are decompositions:

53 + 188189 = 188242
71 + 188171 = 188242
83 + 188159 = 188242
269 + 187973 = 188242
311 + 187931 = 188242
359 + 187883 = 188242
419 + 187823 = 188242
449 + 187793 = 188242

Showing the first eight; more decompositions exist.
