Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612598, here are decompositions:

67 + 31612531 = 31612598
229 + 31612369 = 31612598
397 + 31612201 = 31612598
601 + 31611997 = 31612598
691 + 31611907 = 31612598
757 + 31611841 = 31612598
769 + 31611829 = 31612598
991 + 31611607 = 31612598

Showing the first eight; more decompositions exist.
