Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479350, here are decompositions:

13 + 31479337 = 31479350
43 + 31479307 = 31479350
61 + 31479289 = 31479350
73 + 31479277 = 31479350
79 + 31479271 = 31479350
109 + 31479241 = 31479350
223 + 31479127 = 31479350
277 + 31479073 = 31479350

Showing the first eight; more decompositions exist.
