Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507094, here are decompositions:

7 + 31507087 = 31507094
13 + 31507081 = 31507094
163 + 31506931 = 31507094
271 + 31506823 = 31507094
313 + 31506781 = 31507094
397 + 31506697 = 31507094
571 + 31506523 = 31507094
673 + 31506421 = 31507094

Showing the first eight; more decompositions exist.
