Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530464, here are decompositions:

13 + 31530451 = 31530464
73 + 31530391 = 31530464
283 + 31530181 = 31530464
367 + 31530097 = 31530464
421 + 31530043 = 31530464
463 + 31530001 = 31530464
487 + 31529977 = 31530464
541 + 31529923 = 31530464

Showing the first eight; more decompositions exist.
