Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479194, here are decompositions:

67 + 31479127 = 31479194
163 + 31479031 = 31479194
193 + 31479001 = 31479194
211 + 31478983 = 31479194
283 + 31478911 = 31479194
457 + 31478737 = 31479194
547 + 31478647 = 31479194
601 + 31478593 = 31479194

Showing the first eight; more decompositions exist.
