Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446058, here are decompositions:

5 + 31446053 = 31446058
47 + 31446011 = 31446058
101 + 31445957 = 31446058
167 + 31445891 = 31446058
197 + 31445861 = 31446058
269 + 31445789 = 31446058
569 + 31445489 = 31446058
599 + 31445459 = 31446058

Showing the first eight; more decompositions exist.
