Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619262, here are decompositions:

5 + 31619257 = 31619262
53 + 31619209 = 31619262
71 + 31619191 = 31619262
79 + 31619183 = 31619262
83 + 31619179 = 31619262
139 + 31619123 = 31619262
263 + 31618999 = 31619262
271 + 31618991 = 31619262

Showing the first eight; more decompositions exist.
