Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590626, here are decompositions:

37 + 31590589 = 31590626
43 + 31590583 = 31590626
127 + 31590499 = 31590626
139 + 31590487 = 31590626
157 + 31590469 = 31590626
163 + 31590463 = 31590626
229 + 31590397 = 31590626
283 + 31590343 = 31590626

Showing the first eight; more decompositions exist.
