Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587014, here are decompositions:

73 + 31586941 = 31587014
211 + 31586803 = 31587014
223 + 31586791 = 31587014
271 + 31586743 = 31587014
307 + 31586707 = 31587014
367 + 31586647 = 31587014
397 + 31586617 = 31587014
541 + 31586473 = 31587014

Showing the first eight; more decompositions exist.
