Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479296, here are decompositions:

7 + 31479289 = 31479296
19 + 31479277 = 31479296
223 + 31479073 = 31479296
313 + 31478983 = 31479296
337 + 31478959 = 31479296
577 + 31478719 = 31479296
907 + 31478389 = 31479296
1009 + 31478287 = 31479296

Showing the first eight; more decompositions exist.
