Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499684, here are decompositions:

193 + 31499491 = 31499684
277 + 31499407 = 31499684
283 + 31499401 = 31499684
313 + 31499371 = 31499684
373 + 31499311 = 31499684
457 + 31499227 = 31499684
523 + 31499161 = 31499684
547 + 31499137 = 31499684

Showing the first eight; more decompositions exist.
