Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559132, here are decompositions:

61 + 31559071 = 31559132
139 + 31558993 = 31559132
193 + 31558939 = 31559132
313 + 31558819 = 31559132
373 + 31558759 = 31559132
439 + 31558693 = 31559132
499 + 31558633 = 31559132
613 + 31558519 = 31559132

Showing the first eight; more decompositions exist.
