Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484626, here are decompositions:

83 + 31484543 = 31484626
113 + 31484513 = 31484626
263 + 31484363 = 31484626
359 + 31484267 = 31484626
389 + 31484237 = 31484626
419 + 31484207 = 31484626
449 + 31484177 = 31484626
557 + 31484069 = 31484626

Showing the first eight; more decompositions exist.
