Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620092, here are decompositions:

73 + 31620019 = 31620092
79 + 31620013 = 31620092
103 + 31619989 = 31620092
139 + 31619953 = 31620092
181 + 31619911 = 31620092
223 + 31619869 = 31620092
271 + 31619821 = 31620092
331 + 31619761 = 31620092

Showing the first eight; more decompositions exist.
