Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450364, here are decompositions:

13 + 31450351 = 31450364
73 + 31450291 = 31450364
157 + 31450207 = 31450364
223 + 31450141 = 31450364
271 + 31450093 = 31450364
307 + 31450057 = 31450364
331 + 31450033 = 31450364
373 + 31449991 = 31450364

Showing the first eight; more decompositions exist.
