Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496350, here are decompositions:

29 + 31496321 = 31496350
89 + 31496261 = 31496350
131 + 31496219 = 31496350
227 + 31496123 = 31496350
251 + 31496099 = 31496350
293 + 31496057 = 31496350
401 + 31495949 = 31496350
491 + 31495859 = 31496350

Showing the first eight; more decompositions exist.
