Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484534, here are decompositions:

31 + 31484503 = 31484534
73 + 31484461 = 31484534
157 + 31484377 = 31484534
181 + 31484353 = 31484534
331 + 31484203 = 31484534
373 + 31484161 = 31484534
463 + 31484071 = 31484534
577 + 31483957 = 31484534

Showing the first eight; more decompositions exist.
