Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484642, here are decompositions:

73 + 31484569 = 31484642
109 + 31484533 = 31484642
139 + 31484503 = 31484642
181 + 31484461 = 31484642
193 + 31484449 = 31484642
229 + 31484413 = 31484642
283 + 31484359 = 31484642
433 + 31484209 = 31484642

Showing the first eight; more decompositions exist.
