Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945972, here are decompositions:

11 + 945961 = 945972
23 + 945949 = 945972
29 + 945943 = 945972
31 + 945941 = 945972
43 + 945929 = 945972
73 + 945899 = 945972
89 + 945883 = 945972
149 + 945823 = 945972

Showing the first eight; more decompositions exist.
