Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475548, here are decompositions:

59 + 31475489 = 31475548
89 + 31475459 = 31475548
227 + 31475321 = 31475548
317 + 31475231 = 31475548
359 + 31475189 = 31475548
389 + 31475159 = 31475548
449 + 31475099 = 31475548
479 + 31475069 = 31475548

Showing the first eight; more decompositions exist.
