Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589774, here are decompositions:

3 + 31589771 = 31589774
37 + 31589737 = 31589774
43 + 31589731 = 31589774
67 + 31589707 = 31589774
163 + 31589611 = 31589774
313 + 31589461 = 31589774
367 + 31589407 = 31589774
373 + 31589401 = 31589774

Showing the first eight; more decompositions exist.
