Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472132, here are decompositions:

79 + 31472053 = 31472132
103 + 31472029 = 31472132
193 + 31471939 = 31472132
199 + 31471933 = 31472132
283 + 31471849 = 31472132
421 + 31471711 = 31472132
499 + 31471633 = 31472132
541 + 31471591 = 31472132

Showing the first eight; more decompositions exist.
