Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446302, here are decompositions:

61 + 31446241 = 31446302
73 + 31446229 = 31446302
79 + 31446223 = 31446302
241 + 31446061 = 31446302
271 + 31446031 = 31446302
373 + 31445929 = 31446302
439 + 31445863 = 31446302
661 + 31445641 = 31446302

Showing the first eight; more decompositions exist.
