Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595060, here are decompositions:

61 + 31594999 = 31595060
73 + 31594987 = 31595060
97 + 31594963 = 31595060
157 + 31594903 = 31595060
193 + 31594867 = 31595060
199 + 31594861 = 31595060
313 + 31594747 = 31595060
331 + 31594729 = 31595060

Showing the first eight; more decompositions exist.
