Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590898, here are decompositions:

5 + 31590893 = 31590898
11 + 31590887 = 31590898
107 + 31590791 = 31590898
167 + 31590731 = 31590898
239 + 31590659 = 31590898
281 + 31590617 = 31590898
347 + 31590551 = 31590898
419 + 31590479 = 31590898

Showing the first eight; more decompositions exist.
