Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506044, here are decompositions:

13 + 31506031 = 31506044
61 + 31505983 = 31506044
223 + 31505821 = 31506044
277 + 31505767 = 31506044
307 + 31505737 = 31506044
313 + 31505731 = 31506044
421 + 31505623 = 31506044
523 + 31505521 = 31506044

Showing the first eight; more decompositions exist.
