Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498622, here are decompositions:

31 + 31498591 = 31498622
73 + 31498549 = 31498622
109 + 31498513 = 31498622
151 + 31498471 = 31498622
349 + 31498273 = 31498622
409 + 31498213 = 31498622
433 + 31498189 = 31498622
499 + 31498123 = 31498622

Showing the first eight; more decompositions exist.
