Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612298, here are decompositions:

97 + 31612201 = 31612298
229 + 31612069 = 31612298
457 + 31611841 = 31612298
541 + 31611757 = 31612298
631 + 31611667 = 31612298
691 + 31611607 = 31612298
811 + 31611487 = 31612298
859 + 31611439 = 31612298

Showing the first eight; more decompositions exist.
