Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589924, here are decompositions:

97 + 31589827 = 31589924
151 + 31589773 = 31589924
193 + 31589731 = 31589924
241 + 31589683 = 31589924
313 + 31589611 = 31589924
463 + 31589461 = 31589924
523 + 31589401 = 31589924
547 + 31589377 = 31589924

Showing the first eight; more decompositions exist.
