Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499222, here are decompositions:

61 + 31499161 = 31499222
199 + 31499023 = 31499222
229 + 31498993 = 31499222
373 + 31498849 = 31499222
409 + 31498813 = 31499222
631 + 31498591 = 31499222
673 + 31498549 = 31499222
709 + 31498513 = 31499222

Showing the first eight; more decompositions exist.
