Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479262, here are decompositions:

11 + 31479251 = 31479262
131 + 31479131 = 31479262
179 + 31479083 = 31479262
293 + 31478969 = 31479262
431 + 31478831 = 31479262
863 + 31478399 = 31479262
911 + 31478351 = 31479262
929 + 31478333 = 31479262

Showing the first eight; more decompositions exist.
