Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446182, here are decompositions:

151 + 31446031 = 31446182
199 + 31445983 = 31446182
223 + 31445959 = 31446182
241 + 31445941 = 31446182
331 + 31445851 = 31446182
349 + 31445833 = 31446182
463 + 31445719 = 31446182
541 + 31445641 = 31446182

Showing the first eight; more decompositions exist.
