Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474698, here are decompositions:

5 + 31474693 = 31474698
7 + 31474691 = 31474698
11 + 31474687 = 31474698
29 + 31474669 = 31474698
97 + 31474601 = 31474698
127 + 31474571 = 31474698
139 + 31474559 = 31474698
149 + 31474549 = 31474698

Showing the first eight; more decompositions exist.
