Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613758, here are decompositions:

41 + 31613717 = 31613758
89 + 31613669 = 31613758
131 + 31613627 = 31613758
179 + 31613579 = 31613758
317 + 31613441 = 31613758
347 + 31613411 = 31613758
359 + 31613399 = 31613758
401 + 31613357 = 31613758

Showing the first eight; more decompositions exist.
