Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590242, here are decompositions:

31 + 31590211 = 31590242
109 + 31590133 = 31590242
181 + 31590061 = 31590242
373 + 31589869 = 31590242
631 + 31589611 = 31590242
769 + 31589473 = 31590242
883 + 31589359 = 31590242
991 + 31589251 = 31590242

Showing the first eight; more decompositions exist.
