Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499582, here are decompositions:

151 + 31499431 = 31499582
181 + 31499401 = 31499582
199 + 31499383 = 31499582
211 + 31499371 = 31499582
241 + 31499341 = 31499582
271 + 31499311 = 31499582
421 + 31499161 = 31499582
619 + 31498963 = 31499582

Showing the first eight; more decompositions exist.
