Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506734, here are decompositions:

37 + 31506697 = 31506734
157 + 31506577 = 31506734
211 + 31506523 = 31506734
223 + 31506511 = 31506734
313 + 31506421 = 31506734
367 + 31506367 = 31506734
463 + 31506271 = 31506734
487 + 31506247 = 31506734

Showing the first eight; more decompositions exist.
