Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484002, here are decompositions:

23 + 31483979 = 31484002
83 + 31483919 = 31484002
89 + 31483913 = 31484002
113 + 31483889 = 31484002
131 + 31483871 = 31484002
269 + 31483733 = 31484002
311 + 31483691 = 31484002
353 + 31483649 = 31484002

Showing the first eight; more decompositions exist.
