Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559792, here are decompositions:

73 + 31559719 = 31559792
139 + 31559653 = 31559792
151 + 31559641 = 31559792
349 + 31559443 = 31559792
379 + 31559413 = 31559792
409 + 31559383 = 31559792
421 + 31559371 = 31559792
541 + 31559251 = 31559792

Showing the first eight; more decompositions exist.
