Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499488, here are decompositions:

29 + 31499459 = 31499488
89 + 31499399 = 31499488
101 + 31499387 = 31499488
179 + 31499309 = 31499488
191 + 31499297 = 31499488
197 + 31499291 = 31499488
257 + 31499231 = 31499488
431 + 31499057 = 31499488

Showing the first eight; more decompositions exist.
