Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486848, here are decompositions:

79 + 31486769 = 31486848
97 + 31486751 = 31486848
109 + 31486739 = 31486848
137 + 31486711 = 31486848
139 + 31486709 = 31486848
191 + 31486657 = 31486848
277 + 31486571 = 31486848
311 + 31486537 = 31486848

Showing the first eight; more decompositions exist.
