Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484120, here are decompositions:

61 + 31484059 = 31484120
139 + 31483981 = 31484120
163 + 31483957 = 31484120
193 + 31483927 = 31484120
313 + 31483807 = 31484120
331 + 31483789 = 31484120
397 + 31483723 = 31484120
457 + 31483663 = 31484120

Showing the first eight; more decompositions exist.
