Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461274, here are decompositions:

83 + 31461191 = 31461274
101 + 31461173 = 31461274
113 + 31461161 = 31461274
227 + 31461047 = 31461274
263 + 31461011 = 31461274
347 + 31460927 = 31461274
401 + 31460873 = 31461274
443 + 31460831 = 31461274

Showing the first eight; more decompositions exist.
