Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576136, here are decompositions:

19 + 31576117 = 31576136
127 + 31576009 = 31576136
199 + 31575937 = 31576136
307 + 31575829 = 31576136
313 + 31575823 = 31576136
337 + 31575799 = 31576136
367 + 31575769 = 31576136
409 + 31575727 = 31576136

Showing the first eight; more decompositions exist.
