Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445324, here are decompositions:

61 + 31445263 = 31445324
103 + 31445221 = 31445324
151 + 31445173 = 31445324
283 + 31445041 = 31445324
307 + 31445017 = 31445324
331 + 31444993 = 31445324
433 + 31444891 = 31445324
487 + 31444837 = 31445324

Showing the first eight; more decompositions exist.
