Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503734, here are decompositions:

7 + 31503727 = 31503734
61 + 31503673 = 31503734
103 + 31503631 = 31503734
181 + 31503553 = 31503734
373 + 31503361 = 31503734
397 + 31503337 = 31503734
421 + 31503313 = 31503734
631 + 31503103 = 31503734

Showing the first eight; more decompositions exist.
