Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446122, here are decompositions:

61 + 31446061 = 31446122
139 + 31445983 = 31446122
163 + 31445959 = 31446122
181 + 31445941 = 31446122
193 + 31445929 = 31446122
271 + 31445851 = 31446122
691 + 31445431 = 31446122
769 + 31445353 = 31446122

Showing the first eight; more decompositions exist.
