Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530344, here are decompositions:

3 + 31530341 = 31530344
163 + 31530181 = 31530344
283 + 31530061 = 31530344
367 + 31529977 = 31530344
421 + 31529923 = 31530344
463 + 31529881 = 31530344
673 + 31529671 = 31530344
751 + 31529593 = 31530344

Showing the first eight; more decompositions exist.
