Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479076, here are decompositions:

3 + 31479073 = 31479076
59 + 31479017 = 31479076
107 + 31478969 = 31479076
269 + 31478807 = 31479076
509 + 31478567 = 31479076
593 + 31478483 = 31479076
647 + 31478429 = 31479076
677 + 31478399 = 31479076

Showing the first eight; more decompositions exist.
