Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567292, here are decompositions:

13 + 31567279 = 31567292
61 + 31567231 = 31567292
73 + 31567219 = 31567292
79 + 31567213 = 31567292
139 + 31567153 = 31567292
313 + 31566979 = 31567292
373 + 31566919 = 31567292
499 + 31566793 = 31567292

Showing the first eight; more decompositions exist.
