Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551346, here are decompositions:

5 + 31551341 = 31551346
17 + 31551329 = 31551346
173 + 31551173 = 31551346
257 + 31551089 = 31551346
347 + 31550999 = 31551346
353 + 31550993 = 31551346
467 + 31550879 = 31551346
479 + 31550867 = 31551346

Showing the first eight; more decompositions exist.
