Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601162, here are decompositions:

79 + 31601083 = 31601162
139 + 31601023 = 31601162
193 + 31600969 = 31601162
379 + 31600783 = 31601162
409 + 31600753 = 31601162
421 + 31600741 = 31601162
499 + 31600663 = 31601162
613 + 31600549 = 31601162

Showing the first eight; more decompositions exist.
