Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550446, here are decompositions:

89 + 31550357 = 31550446
107 + 31550339 = 31550446
233 + 31550213 = 31550446
269 + 31550177 = 31550446
293 + 31550153 = 31550446
353 + 31550093 = 31550446
383 + 31550063 = 31550446
419 + 31550027 = 31550446

Showing the first eight; more decompositions exist.
