Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590814, here are decompositions:

11 + 31590803 = 31590814
23 + 31590791 = 31590814
83 + 31590731 = 31590814
131 + 31590683 = 31590814
197 + 31590617 = 31590814
257 + 31590557 = 31590814
263 + 31590551 = 31590814
347 + 31590467 = 31590814

Showing the first eight; more decompositions exist.
