Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188236, here are decompositions:

47 + 188189 = 188236
89 + 188147 = 188236
263 + 187973 = 188236
353 + 187883 = 188236
359 + 187877 = 188236
443 + 187793 = 188236
449 + 187787 = 188236
599 + 187637 = 188236

Showing the first eight; more decompositions exist.
