Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498472, here are decompositions:

3 + 31498469 = 31498472
193 + 31498279 = 31498472
199 + 31498273 = 31498472
283 + 31498189 = 31498472
349 + 31498123 = 31498472
433 + 31498039 = 31498472
463 + 31498009 = 31498472
541 + 31497931 = 31498472

Showing the first eight; more decompositions exist.
