Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498496, here are decompositions:

223 + 31498273 = 31498496
283 + 31498213 = 31498496
307 + 31498189 = 31498496
373 + 31498123 = 31498496
409 + 31498087 = 31498496
457 + 31498039 = 31498496
487 + 31498009 = 31498496
499 + 31497997 = 31498496

Showing the first eight; more decompositions exist.
