Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479598, here are decompositions:

5 + 31479593 = 31479598
41 + 31479557 = 31479598
47 + 31479551 = 31479598
107 + 31479491 = 31479598
131 + 31479467 = 31479598
179 + 31479419 = 31479598
347 + 31479251 = 31479598
401 + 31479197 = 31479598

Showing the first eight; more decompositions exist.
