Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474082, here are decompositions:

151 + 31473931 = 31474082
181 + 31473901 = 31474082
271 + 31473811 = 31474082
349 + 31473733 = 31474082
379 + 31473703 = 31474082
499 + 31473583 = 31474082
751 + 31473331 = 31474082
769 + 31473313 = 31474082

Showing the first eight; more decompositions exist.
