Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945920, here are decompositions:

13 + 945907 = 945920
37 + 945883 = 945920
97 + 945823 = 945920
103 + 945817 = 945920
109 + 945811 = 945920
181 + 945739 = 945920
331 + 945589 = 945920
373 + 945547 = 945920

Showing the first eight; more decompositions exist.
