Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553846, here are decompositions:

13 + 31553833 = 31553846
43 + 31553803 = 31553846
127 + 31553719 = 31553846
139 + 31553707 = 31553846
229 + 31553617 = 31553846
463 + 31553383 = 31553846
487 + 31553359 = 31553846
613 + 31553233 = 31553846

Showing the first eight; more decompositions exist.
