Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486526, here are decompositions:

73 + 31486453 = 31486526
103 + 31486423 = 31486526
109 + 31486417 = 31486526
139 + 31486387 = 31486526
199 + 31486327 = 31486526
223 + 31486303 = 31486526
397 + 31486129 = 31486526
439 + 31486087 = 31486526

Showing the first eight; more decompositions exist.
