Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507374, here are decompositions:

7 + 31507367 = 31507374
11 + 31507363 = 31507374
13 + 31507361 = 31507374
23 + 31507351 = 31507374
53 + 31507321 = 31507374
103 + 31507271 = 31507374
131 + 31507243 = 31507374
163 + 31507211 = 31507374

Showing the first eight; more decompositions exist.
