Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479016, here are decompositions:

47 + 31478969 = 31479016
59 + 31478957 = 31479016
83 + 31478933 = 31479016
449 + 31478567 = 31479016
587 + 31478429 = 31479016
617 + 31478399 = 31479016
683 + 31478333 = 31479016
827 + 31478189 = 31479016

Showing the first eight; more decompositions exist.
