Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550674, here are decompositions:

3 + 31550671 = 31550674
47 + 31550627 = 31550674
101 + 31550573 = 31550674
131 + 31550543 = 31550674
137 + 31550537 = 31550674
227 + 31550447 = 31550674
317 + 31550357 = 31550674
347 + 31550327 = 31550674

Showing the first eight; more decompositions exist.
