Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585634, here are decompositions:

37 + 31585597 = 31585634
97 + 31585537 = 31585634
181 + 31585453 = 31585634
193 + 31585441 = 31585634
307 + 31585327 = 31585634
373 + 31585261 = 31585634
463 + 31585171 = 31585634
541 + 31585093 = 31585634

Showing the first eight; more decompositions exist.
