Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622040, here are decompositions:

59 + 31621981 = 31622040
61 + 31621979 = 31622040
83 + 31621957 = 31622040
139 + 31621901 = 31622040
193 + 31621847 = 31622040
337 + 31621703 = 31622040
347 + 31621693 = 31622040
367 + 31621673 = 31622040

Showing the first eight; more decompositions exist.
