Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590772, here are decompositions:

41 + 31590731 = 31590772
89 + 31590683 = 31590772
113 + 31590659 = 31590772
179 + 31590593 = 31590772
293 + 31590479 = 31590772
359 + 31590413 = 31590772
401 + 31590371 = 31590772
419 + 31590353 = 31590772

Showing the first eight; more decompositions exist.
