Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498382, here are decompositions:

103 + 31498279 = 31498382
109 + 31498273 = 31498382
193 + 31498189 = 31498382
271 + 31498111 = 31498382
313 + 31498069 = 31498382
373 + 31498009 = 31498382
379 + 31498003 = 31498382
499 + 31497883 = 31498382

Showing the first eight; more decompositions exist.
