Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540454, here are decompositions:

13 + 31540441 = 31540454
37 + 31540417 = 31540454
157 + 31540297 = 31540454
193 + 31540261 = 31540454
241 + 31540213 = 31540454
307 + 31540147 = 31540454
331 + 31540123 = 31540454
487 + 31539967 = 31540454

Showing the first eight; more decompositions exist.
