Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496902, here are decompositions:

29 + 31496873 = 31496902
83 + 31496819 = 31496902
233 + 31496669 = 31496902
383 + 31496519 = 31496902
461 + 31496441 = 31496902
641 + 31496261 = 31496902
683 + 31496219 = 31496902
761 + 31496141 = 31496902

Showing the first eight; more decompositions exist.
