Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463162, here are decompositions:

79 + 31463083 = 31463162
139 + 31463023 = 31463162
193 + 31462969 = 31463162
229 + 31462933 = 31463162
331 + 31462831 = 31463162
433 + 31462729 = 31463162
439 + 31462723 = 31463162
571 + 31462591 = 31463162

Showing the first eight; more decompositions exist.
