Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589402, here are decompositions:

43 + 31589359 = 31589402
73 + 31589329 = 31589402
109 + 31589293 = 31589402
151 + 31589251 = 31589402
283 + 31589119 = 31589402
409 + 31588993 = 31589402
709 + 31588693 = 31589402
919 + 31588483 = 31589402

Showing the first eight; more decompositions exist.
