Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496768, here are decompositions:

97 + 31496671 = 31496768
157 + 31496611 = 31496768
181 + 31496587 = 31496768
229 + 31496539 = 31496768
349 + 31496419 = 31496768
379 + 31496389 = 31496768
397 + 31496371 = 31496768
439 + 31496329 = 31496768

Showing the first eight; more decompositions exist.
