Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446362, here are decompositions:

109 + 31446253 = 31446362
139 + 31446223 = 31446362
151 + 31446211 = 31446362
229 + 31446133 = 31446362
331 + 31446031 = 31446362
379 + 31445983 = 31446362
421 + 31445941 = 31446362
433 + 31445929 = 31446362

Showing the first eight; more decompositions exist.
