Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589912, here are decompositions:

43 + 31589869 = 31589912
139 + 31589773 = 31589912
181 + 31589731 = 31589912
229 + 31589683 = 31589912
373 + 31589539 = 31589912
439 + 31589473 = 31589912
619 + 31589293 = 31589912
661 + 31589251 = 31589912

Showing the first eight; more decompositions exist.
