Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484804, here are decompositions:

3 + 31484801 = 31484804
7 + 31484797 = 31484804
157 + 31484647 = 31484804
271 + 31484533 = 31484804
487 + 31484317 = 31484804
523 + 31484281 = 31484804
601 + 31484203 = 31484804
643 + 31484161 = 31484804

Showing the first eight; more decompositions exist.
