Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190748, here are decompositions:

31 + 190717 = 190748
37 + 190711 = 190748
79 + 190669 = 190748
109 + 190639 = 190748
157 + 190591 = 190748
211 + 190537 = 190748
241 + 190507 = 190748
277 + 190471 = 190748

Showing the first eight; more decompositions exist.
