Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981848, here are decompositions:

31 + 981817 = 981848
37 + 981811 = 981848
79 + 981769 = 981848
151 + 981697 = 981848
157 + 981691 = 981848
211 + 981637 = 981848
271 + 981577 = 981848
331 + 981517 = 981848

Showing the first eight; more decompositions exist.
