Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496506, here are decompositions:

17 + 31496489 = 31496506
89 + 31496417 = 31496506
137 + 31496369 = 31496506
383 + 31496123 = 31496506
449 + 31496057 = 31496506
479 + 31496027 = 31496506
557 + 31495949 = 31496506
647 + 31495859 = 31496506

Showing the first eight; more decompositions exist.
