Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486496, here are decompositions:

3 + 31486493 = 31486496
43 + 31486453 = 31486496
73 + 31486423 = 31486496
79 + 31486417 = 31486496
103 + 31486393 = 31486496
109 + 31486387 = 31486496
157 + 31486339 = 31486496
193 + 31486303 = 31486496

Showing the first eight; more decompositions exist.
