Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446030, here are decompositions:

19 + 31446011 = 31446030
47 + 31445983 = 31446030
53 + 31445977 = 31446030
71 + 31445959 = 31446030
73 + 31445957 = 31446030
89 + 31445941 = 31446030
101 + 31445929 = 31446030
113 + 31445917 = 31446030

Showing the first eight; more decompositions exist.
