Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480374, here are decompositions:

5 + 31480369 = 31480374
7 + 31480367 = 31480374
173 + 31480201 = 31480374
257 + 31480117 = 31480374
271 + 31480103 = 31480374
283 + 31480091 = 31480374
313 + 31480061 = 31480374
353 + 31480021 = 31480374

Showing the first eight; more decompositions exist.
