Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484830, here are decompositions:

29 + 31484801 = 31484830
53 + 31484777 = 31484830
59 + 31484771 = 31484830
89 + 31484741 = 31484830
131 + 31484699 = 31484830
317 + 31484513 = 31484830
467 + 31484363 = 31484830
491 + 31484339 = 31484830

Showing the first eight; more decompositions exist.
