Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590158, here are decompositions:

37 + 31590121 = 31590158
97 + 31590061 = 31590158
151 + 31590007 = 31590158
181 + 31589977 = 31590158
331 + 31589827 = 31590158
421 + 31589737 = 31590158
499 + 31589659 = 31590158
547 + 31589611 = 31590158

Showing the first eight; more decompositions exist.
