Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479674, here are decompositions:

3 + 31479671 = 31479674
97 + 31479577 = 31479674
157 + 31479517 = 31479674
337 + 31479337 = 31479674
367 + 31479307 = 31479674
397 + 31479277 = 31479674
433 + 31479241 = 31479674
547 + 31479127 = 31479674

Showing the first eight; more decompositions exist.
