Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606244, here are decompositions:

157 + 31606087 = 31606244
193 + 31606051 = 31606244
331 + 31605913 = 31606244
367 + 31605877 = 31606244
421 + 31605823 = 31606244
433 + 31605811 = 31606244
463 + 31605781 = 31606244
487 + 31605757 = 31606244

Showing the first eight; more decompositions exist.
