Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498466, here are decompositions:

3 + 31498463 = 31498466
193 + 31498273 = 31498466
277 + 31498189 = 31498466
379 + 31498087 = 31498466
397 + 31498069 = 31498466
457 + 31498009 = 31498466
463 + 31498003 = 31498466
487 + 31497979 = 31498466

Showing the first eight; more decompositions exist.
