Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456632, here are decompositions:

43 + 31456589 = 31456632
101 + 31456531 = 31456632
131 + 31456501 = 31456632
191 + 31456441 = 31456632
271 + 31456361 = 31456632
313 + 31456319 = 31456632
353 + 31456279 = 31456632
373 + 31456259 = 31456632

Showing the first eight; more decompositions exist.
