Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484722, here are decompositions:

11 + 31484711 = 31484722
23 + 31484699 = 31484722
179 + 31484543 = 31484722
359 + 31484363 = 31484722
383 + 31484339 = 31484722
419 + 31484303 = 31484722
593 + 31484129 = 31484722
641 + 31484081 = 31484722

Showing the first eight; more decompositions exist.
