Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620088, here are decompositions:

29 + 31620059 = 31620088
107 + 31619981 = 31620088
239 + 31619849 = 31620088
281 + 31619807 = 31620088
317 + 31619771 = 31620088
347 + 31619741 = 31620088
419 + 31619669 = 31620088
557 + 31619531 = 31620088

Showing the first eight; more decompositions exist.
