Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484264, here are decompositions:

61 + 31484203 = 31484264
103 + 31484161 = 31484264
193 + 31484071 = 31484264
283 + 31483981 = 31484264
307 + 31483957 = 31484264
337 + 31483927 = 31484264
457 + 31483807 = 31484264
463 + 31483801 = 31484264

Showing the first eight; more decompositions exist.
