Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484028, here are decompositions:

47 + 31483981 = 31484028
71 + 31483957 = 31484028
101 + 31483927 = 31484028
109 + 31483919 = 31484028
139 + 31483889 = 31484028
151 + 31483877 = 31484028
157 + 31483871 = 31484028
167 + 31483861 = 31484028

Showing the first eight; more decompositions exist.
