Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473992, here are decompositions:

61 + 31473931 = 31473992
181 + 31473811 = 31473992
211 + 31473781 = 31473992
409 + 31473583 = 31473992
463 + 31473529 = 31473992
661 + 31473331 = 31473992
709 + 31473283 = 31473992
751 + 31473241 = 31473992

Showing the first eight; more decompositions exist.
