Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589732, here are decompositions:

73 + 31589659 = 31589732
193 + 31589539 = 31589732
271 + 31589461 = 31589732
331 + 31589401 = 31589732
373 + 31589359 = 31589732
379 + 31589353 = 31589732
439 + 31589293 = 31589732
613 + 31589119 = 31589732

Showing the first eight; more decompositions exist.
