Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573932, here are decompositions:

73 + 31573859 = 31573932
79 + 31573853 = 31573932
101 + 31573831 = 31573932
109 + 31573823 = 31573932
113 + 31573819 = 31573932
139 + 31573793 = 31573932
179 + 31573753 = 31573932
293 + 31573639 = 31573932

Showing the first eight; more decompositions exist.
