Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498922, here are decompositions:

43 + 31498879 = 31498922
73 + 31498849 = 31498922
109 + 31498813 = 31498922
181 + 31498741 = 31498922
283 + 31498639 = 31498922
331 + 31498591 = 31498922
373 + 31498549 = 31498922
409 + 31498513 = 31498922

Showing the first eight; more decompositions exist.
