Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553340, here are decompositions:

19 + 31553321 = 31553340
61 + 31553279 = 31553340
67 + 31553273 = 31553340
79 + 31553261 = 31553340
107 + 31553233 = 31553340
127 + 31553213 = 31553340
139 + 31553201 = 31553340
157 + 31553183 = 31553340

Showing the first eight; more decompositions exist.
