Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552118, here are decompositions:

61 + 31552057 = 31552118
139 + 31551979 = 31552118
181 + 31551937 = 31552118
337 + 31551781 = 31552118
397 + 31551721 = 31552118
541 + 31551577 = 31552118
571 + 31551547 = 31552118
601 + 31551517 = 31552118

Showing the first eight; more decompositions exist.
