Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499544, here are decompositions:

7 + 31499537 = 31499544
47 + 31499497 = 31499544
53 + 31499491 = 31499544
113 + 31499431 = 31499544
137 + 31499407 = 31499544
157 + 31499387 = 31499544
173 + 31499371 = 31499544
233 + 31499311 = 31499544

Showing the first eight; more decompositions exist.
