Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188648, here are decompositions:

157 + 188491 = 188648
211 + 188437 = 188648
241 + 188407 = 188648
331 + 188317 = 188648
337 + 188311 = 188648
349 + 188299 = 188648
367 + 188281 = 188648
541 + 188107 = 188648

Showing the first eight; more decompositions exist.
