Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590098, here are decompositions:

37 + 31590061 = 31590098
61 + 31590037 = 31590098
229 + 31589869 = 31590098
271 + 31589827 = 31590098
367 + 31589731 = 31590098
439 + 31589659 = 31590098
487 + 31589611 = 31590098
691 + 31589407 = 31590098

Showing the first eight; more decompositions exist.
