Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589392, here are decompositions:

53 + 31589339 = 31589392
59 + 31589333 = 31589392
71 + 31589321 = 31589392
89 + 31589303 = 31589392
101 + 31589291 = 31589392
293 + 31589099 = 31589392
449 + 31588943 = 31589392
683 + 31588709 = 31589392

Showing the first eight; more decompositions exist.
