Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479104, here are decompositions:

3 + 31479101 = 31479104
31 + 31479073 = 31479104
43 + 31479061 = 31479104
73 + 31479031 = 31479104
103 + 31479001 = 31479104
193 + 31478911 = 31479104
367 + 31478737 = 31479104
457 + 31478647 = 31479104

Showing the first eight; more decompositions exist.
