Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567148, here are decompositions:

61 + 31567087 = 31567148
181 + 31566967 = 31567148
229 + 31566919 = 31567148
331 + 31566817 = 31567148
439 + 31566709 = 31567148
601 + 31566547 = 31567148
607 + 31566541 = 31567148
631 + 31566517 = 31567148

Showing the first eight; more decompositions exist.
