Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584902, here are decompositions:

73 + 31584829 = 31584902
79 + 31584823 = 31584902
199 + 31584703 = 31584902
379 + 31584523 = 31584902
421 + 31584481 = 31584902
463 + 31584439 = 31584902
541 + 31584361 = 31584902
691 + 31584211 = 31584902

Showing the first eight; more decompositions exist.
