Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620098, here are decompositions:

31 + 31620067 = 31620098
61 + 31620037 = 31620098
79 + 31620019 = 31620098
109 + 31619989 = 31620098
229 + 31619869 = 31620098
277 + 31619821 = 31620098
337 + 31619761 = 31620098
487 + 31619611 = 31620098

Showing the first eight; more decompositions exist.
