Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589612, here are decompositions:

73 + 31589539 = 31589612
139 + 31589473 = 31589612
151 + 31589461 = 31589612
211 + 31589401 = 31589612
283 + 31589329 = 31589612
601 + 31589011 = 31589612
619 + 31588993 = 31589612
661 + 31588951 = 31589612

Showing the first eight; more decompositions exist.
