Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620296, here are decompositions:

67 + 31620229 = 31620296
73 + 31620223 = 31620296
157 + 31620139 = 31620296
229 + 31620067 = 31620296
277 + 31620019 = 31620296
283 + 31620013 = 31620296
307 + 31619989 = 31620296
613 + 31619683 = 31620296

Showing the first eight; more decompositions exist.
