Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981854, here are decompositions:

31 + 981823 = 981854
37 + 981817 = 981854
43 + 981811 = 981854
151 + 981703 = 981854
157 + 981697 = 981854
163 + 981691 = 981854
277 + 981577 = 981854
331 + 981523 = 981854

Showing the first eight; more decompositions exist.
