Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498406, here are decompositions:

127 + 31498279 = 31498406
193 + 31498213 = 31498406
283 + 31498123 = 31498406
337 + 31498069 = 31498406
367 + 31498039 = 31498406
397 + 31498009 = 31498406
409 + 31497997 = 31498406
523 + 31497883 = 31498406

Showing the first eight; more decompositions exist.
