Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496852, here are decompositions:

43 + 31496809 = 31496852
61 + 31496791 = 31496852
73 + 31496779 = 31496852
181 + 31496671 = 31496852
241 + 31496611 = 31496852
313 + 31496539 = 31496852
433 + 31496419 = 31496852
463 + 31496389 = 31496852

Showing the first eight; more decompositions exist.
