Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479526, here are decompositions:

59 + 31479467 = 31479526
107 + 31479419 = 31479526
227 + 31479299 = 31479526
257 + 31479269 = 31479526
443 + 31479083 = 31479526
509 + 31479017 = 31479526
557 + 31478969 = 31479526
569 + 31478957 = 31479526

Showing the first eight; more decompositions exist.
