Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479434, here are decompositions:

13 + 31479421 = 31479434
97 + 31479337 = 31479434
127 + 31479307 = 31479434
157 + 31479277 = 31479434
163 + 31479271 = 31479434
193 + 31479241 = 31479434
307 + 31479127 = 31479434
373 + 31479061 = 31479434

Showing the first eight; more decompositions exist.
