Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567186, here are decompositions:

29 + 31567157 = 31567186
137 + 31567049 = 31567186
347 + 31566839 = 31567186
359 + 31566827 = 31567186
383 + 31566803 = 31567186
389 + 31566797 = 31567186
449 + 31566737 = 31567186
587 + 31566599 = 31567186

Showing the first eight; more decompositions exist.
