Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473898, here are decompositions:

11 + 31473887 = 31473898
59 + 31473839 = 31473898
89 + 31473809 = 31473898
191 + 31473707 = 31473898
317 + 31473581 = 31473898
419 + 31473479 = 31473898
461 + 31473437 = 31473898
647 + 31473251 = 31473898

Showing the first eight; more decompositions exist.
