Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544132, here are decompositions:

43 + 31544089 = 31544132
79 + 31544053 = 31544132
229 + 31543903 = 31544132
349 + 31543783 = 31544132
409 + 31543723 = 31544132
421 + 31543711 = 31544132
463 + 31543669 = 31544132
601 + 31543531 = 31544132

Showing the first eight; more decompositions exist.
