Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499526, here are decompositions:

29 + 31499497 = 31499526
59 + 31499467 = 31499526
67 + 31499459 = 31499526
127 + 31499399 = 31499526
139 + 31499387 = 31499526
197 + 31499329 = 31499526
199 + 31499327 = 31499526
229 + 31499297 = 31499526

Showing the first eight; more decompositions exist.
