Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540626, here are decompositions:

53 + 31540573 = 31540626
97 + 31540529 = 31540626
127 + 31540499 = 31540626
137 + 31540489 = 31540626
263 + 31540363 = 31540626
283 + 31540343 = 31540626
317 + 31540309 = 31540626
409 + 31540217 = 31540626

Showing the first eight; more decompositions exist.
