Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540634, here are decompositions:

3 + 31540631 = 31540634
61 + 31540573 = 31540634
163 + 31540471 = 31540634
193 + 31540441 = 31540634
271 + 31540363 = 31540634
337 + 31540297 = 31540634
373 + 31540261 = 31540634
421 + 31540213 = 31540634

Showing the first eight; more decompositions exist.
