Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479976, here are decompositions:

29 + 31479947 = 31479976
173 + 31479803 = 31479976
233 + 31479743 = 31479976
239 + 31479737 = 31479976
257 + 31479719 = 31479976
383 + 31479593 = 31479976
419 + 31479557 = 31479976
509 + 31479467 = 31479976

Showing the first eight; more decompositions exist.
