Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592132, here are decompositions:

3 + 31592129 = 31592132
79 + 31592053 = 31592132
139 + 31591993 = 31592132
223 + 31591909 = 31592132
349 + 31591783 = 31592132
409 + 31591723 = 31592132
421 + 31591711 = 31592132
619 + 31591513 = 31592132

Showing the first eight; more decompositions exist.
